1. MFi Certified 256GB 3-in-1 – Flexible All-Around Storage
MFi Certified 256GB 3-in-1
256GB storage capacity
Three-in-one connector design
iOS 12.1 minimum
Touch ID encryption
This MFi Certified three-in-one drive is a versatile choice for iPhone users who want one small storage device for phones, tablets, and computers. It carries a 4.4 rating, offers 256GB of capacity, and combines USB, Lightning, and USB-C interfaces. Those qualities make it particularly useful for users who regularly move media among an iPhone, a Mac or PC, and a USB-C Android device.
Pros
- Works across major device types
- Simple one-click backup
- Automatic camera album storage
- Flexible file encryption
- Compact keychain design
Cons
- Requires the U-Disk app
- Lightning limits newer-device flexibility

The drive's most useful feature is its one-click backup workflow. Through the U-Disk app, photos, videos, and phonebook data can be backed up without a conventional data cable or cloud subscription. Its in-app camera can save new captures directly to U-Disk albums in real time, reducing the need to keep every video on internal iPhone storage. Users can also play stored music and movies or share files directly to social platforms.
Security options add meaningful value for a drive used to store personal media. The app can encrypt the entire flash drive with Touch ID or a passcode, or protect selected files instead. The stated construction also emphasizes metal housing, dust resistance, drop resistance, and anti-magnetic performance. These protections are especially relevant for a device that may remain attached to a phone, carried in a pocket, or used while traveling.
The important compromise is that iOS devices must download the U-Disk app, and Lightning is required for direct use with an iPhone. It may also feel less future-facing than a drive built around USB-C. Even so, the combination of 256GB capacity, cross-platform connectors, direct camera storage, and granular encryption makes this a strong general-purpose pick for photographers, travelers, and anyone frustrated by limited phone storage.
Backup That Extends Phone Storage
One-click backup and direct camera storage are the standout benefits. They reduce manual copying and allow media to live on the drive when internal iPhone space becomes tight.
Security for Personal Media
Whole-device or selected-file encryption gives users a practical way to protect sensitive photos, videos, and documents while keeping the drive portable.

2. MFi Certified 128GB 3-in-1 – Compact Backup for Everyday Use
MFi Certified 128GB 3-in-1
128GB storage capacity
Three-in-one connector design
iOS 12.1 minimum
Touch ID encryption
This 128GB MFi Certified drive is a compact option for iPhone users who primarily need to offload photos, short videos, and everyday documents. It has a 4.3 rating and offers the same broad three-interface approach as larger-capacity alternatives: USB for traditional computers, Lightning for compatible iPhones and iPads, and USB-C for compatible devices.
Pros
- Compact cross-platform design
- One-click backup support
- Direct media playback
- Selectable encryption
- Included keychain
Cons
- Less space than 256GB models
- Requires the U-Disk app
We may earn a commission when you buy through this link, at no additional cost to you.
Its app supports one-click backups of photos, videos, and phonebook information, while the in-app camera can save captures directly to U-Disk albums. That makes the drive useful for people who want to maintain a separate media backup without uploading everything to an online account. Stored movies and music can also be accessed while traveling or away from a computer.
The encryption menu can protect either the entire drive or specific files with Touch ID or a passcode. Its stated metal construction and resistance to dust, drops, and magnetic interference suit frequent mobile use. The included keychain makes it easier to keep the small storage device attached to a bag, keys, or other everyday gear.
The central trade-off is capacity. At 128GB, it is better suited to rotating a smaller collection of files than storing an extensive high-resolution video archive. It also depends on the U-Disk app for iOS operation. For someone who needs a lightweight daily backup drive rather than maximum storage, this remains a balanced and convenient option.
A Small Drive for Daily Backups
The 128GB capacity works well for users who regularly clear space and need a rotating collection of recent photos, videos, and documents.
Useful Cross-Platform Connectivity
USB, Lightning, and USB-C connectors let the same drive move between an iPhone, computer, and compatible Android device with less need to carry separate media.

3. SANDISK 256GB Phone Drive – Best Overall Flash Drives for iPhone
SANDISK 256GB Phone Drive
256GB storage capacity
USB-C and Lightning
Manual and automatic backups
Password file encryption
The SANDISK 256GB Phone Drive is a strong overall choice because it supports both USB-C and Lightning iPhones rather than limiting compatibility to one connector generation. It is made for iPhone 15 or newer USB-C devices and iPhone 14 or older Lightning models. The 4.3-rated product is particularly attractive to users who expect to change phones or work across multiple iPhone generations.
Pros
- Supports modern and older iPhones
- Automatic backup capability
- Real-time progress tracking
- Works with iOS Files
- Password-protected encryption
Cons
- Memory Zone app required
- Some functions need firmware updates
We may earn a commission when you buy through this link, at no additional cost to you.
Its SANDISK Memory Zone app provides both manual and automatic backup options. Progress tracking helps users understand what is happening during long transfers, while background multitasking and partial backup support can help when iPhone storage is already constrained. When connected through USB-C, the drive can also be accessed through the Memory Zone app or the native iOS Files app, reducing dependence on a single interface.
File movement is supported between compatible USB-C or Lightning iPhones, iPad Pro, Mac, and other compatible devices. The ability to transfer files, reclaim internal storage, and add password-protected encryption gives this drive a well-rounded feature set. The app may also prompt users to update firmware, which is an extra setup step but intended to optimize file-management performance.
This is a good recommendation for iPhone users who value clear backup controls, broad device coverage, and a recognized storage brand. Its limitation is dependence on the Memory Zone app for the fullest functionality, including backup and Lightning copy operations. Even so, the combination of 256GB, two iPhone connectors, automatic backup, and security features makes it the most balanced pick in this guide.
Broad iPhone Generation Support
Matching USB-C and Lightning connectors allows the drive to serve newer and older supported iPhones, which is valuable for households or teams with mixed devices.
Backup Controls That Fit Real Workflows
Manual and automatic options, progress tracking, background support, and partial backups provide useful flexibility when storage or time is limited.

4. Lexar D50E 128GB Dual Drive – Fast USB-C Storage for Newer iPhones
Lexar D50E 128GB Dual Drive
128GB storage capacity
USB-A and USB-C
Up to 400MB/s reads
Cable-free metal housing
The Lexar D50E is a high-speed dual drive with a 4.6 rating, the highest among the products reviewed. It uses built-in USB-A and USB-C connectors, making it especially suitable for USB-C iPhones, USB-C iPads, Macs, and modern computers. The absence of Lightning means it is not a direct solution for older iPhone models, but it targets users who have moved to USB-C devices.
Pros
- Highest stated rating
- Very high transfer speeds
- Compact cable-free design
- Durable metal enclosure
- iOS and Android photo backup
Cons
- No Lightning connector
- iCloud backup unsupported
We may earn a commission when you buy through this link, at no additional cost to you.
Lexar states transfer speeds of up to 400MB/s for reading and 360MB/s for writing. Those figures describe a direct computer-to-drive workflow and may differ when files pass through a phone or other host device. Even with that qualification, the claimed performance is positioned for large photo collections, high-resolution video, and other storage-heavy transfers, while the solid-state design helps make the unit compact and cable-free.
The free Lexar App includes a photo backup function for iOS and Android. That makes the drive more than a basic file mover, although the product information explicitly states that iCloud content backup is not supported. A durable metal housing protects both connectors, and capacities are offered beyond this 128GB version for buyers who need a larger media library.
This is a compelling pick for owners of USB-C iPhones who prioritize speed and a clean, pocketable design over broad iPhone-generation support. It is less suitable for anyone with a Lightning iPhone or for users seeking a full iCloud replacement. Subject to those constraints, the D50E offers impressive stated performance and a useful photo-backup app.
Speed for Large Media Collections
The high stated read and write speeds suit photographers and video creators who regularly move substantial files between compatible USB-C devices and computers.
Designed for Modern Connections
The dual USB-A and USB-C layout eliminates loose caps, while the durable housing protects the connectors during transport.

5. MFi Certified 256GB Blue Drive – Four-Interface Mobile Storage
MFi Certified 256GB Blue Drive
256GB storage capacity
Four-interface connector system
iOS 12.1 minimum
Retractable connector design
This 256GB MFi Certified flash drive is built for people who move between many kinds of devices. It has a 4.1 rating and includes USB, Lightning, Micro USB, and Type-C interfaces, with Type-C available as a standalone adapter. That unusually broad connector selection is useful for legacy equipment as well as modern phones and computers.
Pros
- Supports four connector types
- Retractable protected design
- One-click backup workflow
- Direct media playback
- File and app encryption
Cons
- Lowest rating in the group
- Adapter-based connector system
We may earn a commission when you buy through this link, at no additional cost to you.
Its frosted aluminum construction and retractable design help protect the main connector while reducing the chance of losing it. A keychain is attached for easier carrying. After downloading the required app on iPhone, users can back up multiple videos, pictures, and documents with one click, store new media without occupying internal phone memory, and play compatible music and video files from the drive.
The product also supports file and app encryption, adding privacy for sensitive content. Broad compatibility extends to iOS 12.1 or later, OTG Android phones, and computers with USB ports. This makes it a good media-transfer device for a traveler or content professional carrying more than one phone format, although the extra adapters may be less convenient than a permanently attached Lightning connector.
The drive's 4.1 rating is the lowest in this selection, and its 256GB label may display slightly differently after formatting because manufacturers and computers use different capacity calculations. Those are worthwhile points to consider, but they do not outweigh the extensive connector coverage, one-click backup, and encryption options. It is best for buyers who value versatility over the newest connector design.
One Drive for Multiple Connector Types
Adding Micro USB alongside USB, Lightning, and Type-C makes this model useful for older phones, current devices, and computers.
Portable Connector Protection
The retractable design and attached keychain help protect the drive and reduce the likelihood of leaving it behind during travel.

6. Lexar D40E 128GB Dual Drive – Compact Encrypted USB-C Storage
Lexar D40E 128GB Dual Drive
128GB storage capacity
USB-A and USB-C
Up to 100MB/s transfers
256-bit AES encryption
The Lexar D40E is a compact USB-C and USB-A drive that works with USB-C iPhones and iPads, but it does not include a Lightning connector. Its 4.3 rating and stated transfer speed of up to 100MB/s make it a practical general-purpose option for moving files between newer Apple devices, computers, and compatible peripherals.
Pros
- Swivel design protects connectors
- Broad computer compatibility
- No software installation required
- Advanced AES encryption
- Lightweight metal enclosure
Cons
- No Lightning connector
- Not designed for iPhone backup
We may earn a commission when you buy through this link, at no additional cost to you.
The 360-degree swivel design keeps the active connector covered while revealing the other connector when needed. That removes the need for a loose cap. Its metal enclosure, 26-gram weight, and compact dimensions make it easy to carry, while the stated operating-temperature range covers common indoor and travel conditions.
Plug-and-play operation is another advantage because no installation is required for compatible USB-C and USB-A systems. Advanced security software with 256-bit AES encryption helps protect files, and the product is backed by a three-year limited warranty. These features make the D40E more suitable as secure everyday mobile storage than as a specialized automated photo-backup device.
It is not the right choice for an iPhone user with a Lightning connector or someone who needs app-assisted iPhone backup. For a USB-C iPhone owner who mainly wants a simple, encrypted drive for documents, media, and computer transfers, however, the compact swivel design, broad device support, and straightforward operation are all compelling.
Swivel Convenience Without Caps
Rotating between USB-C and USB-A keeps both interfaces protected and avoids the small caps that are easily misplaced.
Encryption for Everyday Files
Support for 256-bit AES encryption adds a useful layer of privacy for documents and personal media stored on the drive.

7. 512GB USB-C Photo Stick – Best Premium Flash Drive for iPhone
512GB USB-C Photo Stick
512GB storage capacity
USB-C and iOS connectors
mFlash app required
USB-A adapter included
The 512GB USB-C Photo Stick is the premium capacity option in this guide, combining a 4.5 rating with enough room for a substantial photo and video library. It pairs a USB-C connector with a Type-iOS connector for compatible phones, tablets, and computers, making it relevant to both modern USB-C iPhones and Lightning-equipped iPhones.
Pros
- Generous 512GB capacity
- Backs up photos and videos
- Supports iPhone and iPad
- Includes USB-A adapter
- No iCloud reliance
Cons
- Requires the mFlash app
- No Micro-USB support
We may earn a commission when you buy through this link, at no additional cost to you.
Using the mFlash app, users can back up photos, videos, and files, then manage, copy, and transfer media on an iPhone or iPad. The drive is positioned as a way to preserve important memories and free internal storage without depending entirely on cloud storage. An included USB-A adapter expands its usefulness with laptops, desktop computers, and other USB-A equipment.
The 512GB capacity is the main differentiator. It is more appropriate than smaller drives for photographers, frequent video creators, or users who want to keep a large offline collection and rotate only essential files. The device also supports music and documents, so it can function as general-purpose mobile storage rather than a photo-only accessory.
Compatibility requires attention. The mFlash app and permission to access photos and files are necessary for iPhone and iPad backups, while compatible Android and PC systems can use the drive as external storage without the app. It is not compatible with Micro-USB devices. For buyers who need high capacity, flexible connectors, and dependable app-based file management, this is a strong premium recommendation.
Room for a Larger Media Archive
The 512GB capacity gives users more freedom to retain high-resolution photos and videos without moving every file into a phone's limited internal storage.
App-Based File Management
The mFlash app centralizes copying, backup, and organization, making the drive easier to manage across iPhone and iPad workflows.

8. MFi Certified 256GB Silver Drive – Direct Camera Backup with Encryption
MFi Certified 256GB Silver Drive
256GB storage capacity
USB, Lightning, USB-C
Up to 80MB/s reads
Individual file encryption
This MFi Certified 256GB drive is a direct-to-iPhone storage option with USB, Lightning, and Type-C interfaces. Its 4.1 rating places it behind several alternatives, but the feature set remains substantial: one-click backups, direct media playback, social sharing, and individual file encryption make it useful for everyday mobile storage and content sharing.
Pros
- Large 256GB capacity
- One-click photo backup
- Direct video playback
- Three connector formats
- Individual file encryption
Cons
- Lower 4.1 rating
- Capacity display may vary
We may earn a commission when you buy through this link, at no additional cost to you.
The drive supports iOS 12.1 and later, compatible OTG Android phones, and computers with USB ports. Once the companion app is installed on iPhone or iPad, users can back up photos, videos, and phonebook data and save large media away from internal storage. Stated performance reaches up to 80MB/s for reading and 40MB/s for writing, though actual results depend on the connected device and workflow.
Metal construction is paired with stated resistance to water, dust, drops, high temperatures, and magnetic interference. A keychain design helps reduce loss risk. Users can share stored photos, videos, and documents to platforms such as Facebook and Twitter, while encryption can be applied to important files that require additional protection.
The main drawbacks are the relatively low rating and a note that the displayed capacity may differ because manufacturers use decimal calculations while computers use binary calculations. Some space is also needed for formatting and system functions. Even with those caveats, the 256GB capacity, useful app, and one-click backup make this a reasonable choice for iPhone users who want dedicated media and document storage.
Automatic Space Savings
One-click backup and support for storing videos and photos outside the phone reduce pressure on internal iPhone storage.
Targeted File Protection
Individual file encryption is useful when a user wants to protect selected documents or media without locking the entire drive.

9. SSK 256GB Dual Drive – High-Speed Storage for USB-C Workflows
SSK 256GB Dual Drive
256GB storage capacity
USB-C and USB-A
Up to 550MB/s reads
EXFAT default format
The SSK 256GB dual drive delivers the highest stated read speed in the group at up to 550MB/s, with write speeds of up to 500MB/s. It has a 4.4 rating and built-in USB-C and USB-A 3.2 connectors. This makes it a high-speed option for USB-C iPhones and iPads, although it is explicitly incompatible with Lightning ports.
Pros
- Extremely high stated read speed
- Large 256GB capacity
- No software installation required
- Protective dual-head cover
- Broad device compatibility
Cons
- Lightning connector incompatible
- Performance varies by host
We may earn a commission when you buy through this link, at no additional cost to you.
Its plug-and-play design requires no software installation, and the drive can expand storage or move pictures and movies on compatible Android devices, MacBooks, Windows computers, smart TVs, and car audio systems. The EXFAT default format supports use across Windows, Linux, Mac OS, and compatible Android systems, while backward compatibility with USB 3.0 and USB 2.0 broadens its reach.
The zinc alloy shell is designed to resist falls and abrasion, and a double-head protective cover helps shield both interfaces. Heat dissipation and shock resistance are additional stated benefits. Its speed is especially attractive for users who routinely work with high-resolution images and video, though results can vary depending on host equipment, interfaces, and user settings.
This drive is best for a USB-C iPhone 15 or newer user who needs fast direct file access and frequently transfers to modern computers. It cannot serve an older Lightning iPhone and does not provide the app-driven automatic backup workflow of dedicated iPhone models. Subject to that connector limitation, its speed and 256GB capacity make it a strong performance-oriented choice.
High-Speed Transfers for Large Files
The stated 550MB/s read and 500MB/s write capabilities suit users who regularly move large photos, videos, and project files.
Broad System and Media Support
USB-C, USB-A, backward compatibility, and EXFAT make the drive useful across computers, mobile devices, smart TVs, and car systems.

10. EATOP 256GB Rose Pink Drive – App-Free iPhone File Management
EATOP 256GB Rose Pink Drive
256GB storage capacity
Four independent connectors
iOS 13 minimum
No app required
The EATOP 256GB drive stands out for requiring no third-party app on iPhone or iPad. It has a 4.2 rating and works through the native Files app, offering a more direct way to copy photos, videos, contacts, and documents. That makes it appealing to users who do not want to install additional software or grant a third-party app broad access to their media.
Pros
- No iOS companion app
- Works through native Files
- Supports photos, contacts, documents
- Four independent connector ports
- Direct social media sharing
Cons
- Lower stated transfer speeds
- Phone cases may block connection
We may earn a commission when you buy through this link, at no additional cost to you.
USB, USB-L, Micro USB, and USB-C independent ports provide extensive device support. The drive is compatible with iPhone, iPad, Android OTG phones, laptops, and tablets, and it works without an internet connection. Its stated read speed reaches 30MB/s, with lower write performance, which is more modest than the high-speed computer-oriented drives in this list but appropriate for routine media transfers.
The native Files workflow is straightforward. On an eligible iPhone or iPad running iOS 13 or later, users insert the drive, open Files, return to Browse, and locate the drive named Untitled. Files can then be moved between the drive and device. Compatible Android phones should have OTG enabled and access the drive through File Manager, while PC users can treat it as external storage.
One practical concern is that a thick phone case may physically prevent the connector from seating correctly. Removing the case can resolve recognition problems. Available capacity may also appear lower because formatting and other functions occupy space. Even with these caveats, the no-app approach and native Files support make this a convenient pick for iPhone users who prioritize simplicity.
Native Files App Simplicity
Because no companion app is required on iPhone or iPad, users can manage the drive through the familiar Files interface.
Connectivity Without a Cloud Dependency
The drive enables local transfers and backups without requiring an internet connection or ongoing cloud-storage subscription.

Buying Guide – How to Choose the Best Flash Drives for iPhone
The most important buying factors are connector compatibility, required software, usable storage, backup behavior, and the types of files you need to move. A drive that works well with a computer may still be inconvenient for an iPhone if it lacks a native mobile workflow.
Lightning Versus USB-C Compatibility
Choose the connector that matches your actual devices, and consider a multi-interface model if your setup will change.
App Requirements and User Experience
Verify the app requirement before buying, then choose convenience and backup features over the workflow you actually prefer.
Realistic Storage Capacity
Match capacity to your media volume, leaving room for future files and the small amount of space used by formatting.
Backup and Automatic Camera Features
Prioritize automatic backup if consistency is your main goal; choose manual access if you rarely need recurring transfers.
Transfer Speed and Host Dependence
Treat maximum speed as a conditional claim and prioritize reliable operation on your actual iPhone and computer.
Encryption and Physical Protection
Choose at least one credible privacy feature for personal files and a connector design that is protected during transport.
Cross-Device Flexibility
Add only the connectors you will regularly use if portability matters most; include more when cross-device transfer is essential.
Portability and Everyday Handling
Choose a size and closure style that you will actually carry, and test whether your phone case interferes.
How to Use and Care for Your Flash Drives for iPhone
Before the first transfer, confirm that the drive's connector matches your iPhone, install any required app from the App Store, and grant it permission to access the photos, videos, and files you intend to manage. For a drive that appears through the native Files app, insert it, open Files, return to Browse, and select the drive. For app-based products, follow the manufacturer's setup instructions and update the app or firmware if prompted.
When backing up, begin with a smaller test group to confirm the workflow and available space. Use the app's manual, automatic, or one-click option as appropriate, and avoid disconnecting the drive while a transfer is active. If a device does not recognize the drive, remove the phone case, reconnect it securely, and confirm that the required permissions and app are installed. Never format the drive through an unrelated device while important files are still stored on it.
To keep the drive reliable, use the attached cap, retractable mechanism, swivel cover, or connector protection exactly as designed. Eject it through the Files app or computer interface before removal, and do not pull it out while data is being written. Store it in a dry place away from magnets and extreme heat, and keep a separate backup of irreplaceable files. Encrypt sensitive material, avoid using the drive as the only copy of important data, and periodically verify that older files can still be read.
Frequently Asked Questions
Do I need a Lightning flash drive for my iPhone?
The required connector depends on the iPhone model. iPhone 14 and older devices generally use Lightning, while iPhone 15 and newer models use USB-C. A USB-C drive therefore does not connect directly to an older iPhone, and a Lightning drive will not serve a newer USB-C iPhone. Choosing a model with both connectors is useful if you own multiple iPhone generations.
Can I use a regular USB flash drive with an iPhone?
Only when the iPhone has a compatible physical connector and the device supports external storage access. A USB-A drive cannot plug directly into an iPhone, and a USB-C drive still needs compatible mobile file-management support. Dedicated iPhone flash drives use built-in or attached Lightning or USB-C connectors and provide the appropriate app or Files integration.
Which flash drives work without an app?
The EATOP 256GB model in this guide is designed to work with iPhone and iPad through the native Files app without a third-party app. Most other MFi Certified and branded options require a companion app for their full backup, camera, encryption, or file-management features. Check the compatibility notes before ordering if avoiding software installation is important.
How much storage do I need for iPhone photos and videos?
The right amount depends on whether you are creating a temporary backup, maintaining a rotating library, or archiving large 4K video files. A 128GB drive is useful for recent media, while 256GB provides more room for photographers and frequent travelers. A 512GB drive is better suited to extensive libraries and users who want to offload media without constant deletion. Actual available space can be lower than the labeled capacity.
Can I directly play videos from an iPhone flash drive?
Several products in this guide support direct playback of stored movies and music through their iPhone apps. Playback depends on the file format, codec, app compatibility, and available device resources. If you regularly work with less common formats, verify that the drive can handle them or keep an additional copy in a widely supported format.
Why does my iPhone not recognize the flash drive?
First, confirm that you have the correct connector for the iPhone model. Then remove the phone case if it may be blocking the plug, reinstall or update the required app, and verify that photo and file permissions are enabled. Restarting the iPhone can also help. Native Files access may require you to return to Browse and select the drive manually.
Are MFi Certified flash drives better for iPhone?
MFi certification indicates that the accessory has been designed and produced with appropriate Apple ecosystem compatibility standards. It can provide greater confidence in connector and accessory compatibility, but it does not remove the need to check iOS version, app requirements, and file-management features. Non-MFi USB-C options can still be useful for newer iPhones when their mobile workflow is supported.
Can a flash drive replace all of my iPhone cloud storage?
A flash drive can provide local extra storage and reduce the amount of media kept on the iPhone, but it is not automatically a complete cloud replacement. Some drive apps do not support iCloud content backup, and physical media can be lost or damaged. For irreplaceable files, maintain more than one copy and use a flash drive as part of a broader backup strategy.
Final Thoughts on Choosing the Best Flash Drives for iPhone
The SANDISK 256GB Phone Drive is the strongest overall recommendation because it combines USB-C and Lightning support with manual and automatic backups, progress tracking, and file encryption. The MFi Certified 256GB three-in-one model is a flexible budget choice with one-click backup and direct camera storage, while the 512GB USB-C Photo Stick offers the most generous premium capacity for large media collections.
Before choosing, prioritize the connector that matches your iPhone, confirm whether a companion app is required, and decide whether you need simple file access or an automatic backup workflow. Capacity matters, but reliable connection, useful software, appropriate permissions, and secure storage are equally important. USB-C-only high-speed drives can be excellent for newer iPhones, while Lightning-equipped models serve older devices and mixed phone collections.
Finally, review the current listing details, current prices, included accessories, and compatibility notes before purchasing. Product availability and software requirements can change, and a phone case may affect physical connection. Use the drive for local storage and transfers, keep additional backups of irreplaceable files, and select the model whose connector and workflow best match the devices you use every day.
