Customers are saying

Customers find value in the product's ample storage, fast speed, and overall strong performance, often highlighting its ease of use and good price. The USB 3.0 capabilities are also appreciated, along with its comfortable size. However, a small number of customers have noted minor concerns regarding heat during data transfer and the design of the retracting case.

    I bought the 3.0 for faster transfers, it's great! I also wanted a different color besides black. Transferring data on the 3.0 is much faster than the 2.0 usb's. I like it so much I purchased a 128GB usb 3.0.

    Works great, and has lots of storage space. I also really like the retractable feature that means the drive connector is safe from damage but one doesn't have to keep track of a cap

    School started and a lot of writing essays, reports, short writings. This little device can hold a lot of paper work. It even saves videos that they have to watch to write reports on. It's a handy tool for school

    Nice high quality high capacity memory stick. Wanted to be able to keep back-ups of photos on a long trip and these were enough to cover two cameras for three weeks.

    An amazingly small thing that holds so much. I am using it to backup my backup disk just to add one more layer of safety. Its like carrying a Library around in your pocket! Who woulda ever known!

    I use thumb drives daily, so it was a no brainer to pickup multiple 64 GB drives. Being able to carry about a ton of data on these drives and having duplicates is very important to me. I've never had one fail!
