Super handy device. Much easier and faster than trying to transfer photos from my phone to my computer via a data USB cord which is quite slow and cumbersome. This is also tiny and easy to keep with you. At 256 GB this will hold a lot of photos and videos and makes it easy to share, copy, save to computer, or just store your photos so they aren't filling up your phone storage. I've always had good luck with SanDisk products and most all of my flash drives, cards, and readers are SanDisk. This is very sturdy, well made, and the spinning cover is perfect for protecting the end and easy to switch between the C and the A USBs. Well worth the price.

This works both on macOS (Yosemite all the way up to Sonoma) and Windows (10, 11). I am able to easily transfer and work with (print, edit) files on this flash drive no matter which system I am using. I have also used this drive while plugged into my iPhone 15 and it works just fine. Using the Files app and browsing to the flash drive, I can see and open the files on it with no problem. The entire device itself is quite small and portable, so it fits in any pocket, pouch, or on any keychain without taking up a lot of space. While I have only been using it for a short while (three weeks), it has always been available and reliable, with no hiccups or complaints from either Windows or macOS about the drive not being visible/readable/ready. The only reason this is not a 5-star item is the physical design. I like that you can have either side/connector (USB-A or USB-C) out/open by spinning the flash drive, but that also means that whichever side is out is exposed. This device DOES NOT come with any kind of dust/protective cover for either connector. For that matter, the side that is not exposed isn't exceedingly well protected either, but it is better than nothing. I would like it if the device came with protective caps for the connectors or allowed you to control exposure of the connector ends. Shy of that one issue (lack of dust covers for connectors), this is a very good flash drive.

You must download the app (free) and it’s SO EASY to transfer files from your phone. I have an iPhone and I no longer need to buy cloud storage. After photos/videos are copied to the thumb drive, the Sandisk app will ask to delete the ones on your phone automatically after they’ve been backed up. I love it. SEEMLESS. Perfect!

Needed a large enough USB storage device that would work both as an OTG device for backing up phone data off multiple devices, but also on standard PC's if necessary. This was the perfect choice. On one end is USB-C male connector, which actually has a longer metal plug. This make it easier to fit the USB-C port on the phone without taking off the phone case. The other end is a standard USB-A male connector that is also longer and can be inserted into recessed ports on a PC or laptop. The physical drive itself is tiny. And the casing is plastic (not metal). So it's extremely lightweight, and narrow enough so that it can actually fit inside the cap of fountain-pen. The only complain I have is the SanDisk software on Android. It kept failing to recognize the exFAT format that was default on the drive. After some troubleshooting, I realized that the drive first had to be formatted by Android (via Android OS's Storage setting), and not via Windows OS. Once the blank drive was formatted via native Android's Storage option for exFAT, it worked on Android across multiple phones, and also in Windows. Otherwise this software issue, this device was perfect for my needs.

Excellent solution for extra file storage removing files from phone, yet keeping them at hand and accessible by both phone and computer, Dependable and good value!

Great Sandisk quality. Tiny size, fits either USB connection. Easily recognized and formatted for MacIS Time Machine backup.

Excelente, es rápida para pasar archivos. Un poco pequeña de tamaño, para los que son olvidadizos tengan cuidado.

Working for about 2-3 minutes, after which it stops working and the stick is not available on Windows. Probably broken, this is why it's refurbished.

Pequeña y súper rápida. Cuenta con puerto tipo C y tipo A.

Sanfusk mantendo a qualidade!

Very handy having both a usb and type c port. Has a short installation app for phones but great for that easy access when it has two ports to plug and play. Very compact! So small in fact that I have to clip it with a keychain so it doesn't disappear on me, but that's a compliment!
