Review: I finally have space on my iPhone - Took a chance and ordered this after having bad luck with another brand. I used it to transfer files from my iPhone 16 to my laptop. It worked great! I never thought I would see the day when I was down to 85 GB out of 128 GB on my phone! I just transferred all my videos to the device and then from the device to my laptop. If you're someone that is daily getting those messages that you're out of storage space or you can't even download the next iOS version because you're out of space, I highly recommend this for transferring your files!
Review: Wonderful purchase - It works, My phone storage was 96 percent. I transferred some videos from my phone to the flash drive and freed up storage space to 70 percent. Will be transferring more stuff to it. The size is very small but convenient to carry around. The set up was easy and transfer was quick. It is reliable and will definitely be of great benefit. Price was good. I also like the fact that I can use the C part on my phone and the A part on my desktop. Definitely great purchase

### ⭐⭐⭐⭐⭐ Small but with a large capacity
*by M***A on July 6, 2026*

This usb drive is very small but transfers are reasonably quick for a flash drive and the capacity is large. There are both usba-c and usb-a connectors so it works with both my old and new computers. I am satisfied with the purchase.
