Customers are saying

Customers consistently note the Ultra 64GB USB 3.0 Flash Drive's ample storage capacity, ease of use, and competitive price as significant advantages. Many appreciate its fast transfer speeds thanks to the USB 3.0 interface and convenient size. While some users mentioned the drive can get warm during extensive use, and a few expressed concerns about the design of the retractable case, the positive feedback on storage, speed, and value outweighs these drawbacks. The bright color is also frequently praised for easy identification.

    I was astonished at the read and write speeds for this USB drive, I don't think I can go back to 2.0 anymore - I guess that's with anything, i.e. HD, today's internet speeds.

    This works great, so much faster then my old flash drive. This is so much faster then my old 2.0 flash drive, Its been so nice to be able to download large files faster. The casing is nice that's its in as well, feels sturdy and well made. I don't need to worry about it getting messed up in the pocket.
