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 even get as crazy as pulling this flash drive out before properly 'ejecting' it from my PC- and I have never had a problem. The USB retracts into the housing thus providing added protection to the male insert end. In the end, this has been the most hardware-stable and reliable flash drive that I have owned.
