This a great product the transfer rates are blazing fast when working with large file sizes. It's easy to toss in a pocket and forget about until you need it. The only issues I've had are more are more of the physical construction. The outer and backside are gripped with a rubber that is great for your hands but terrible if around dust. Everything sticks to it, especially anything found in your pockets. The plastic front side feels hollow and made of thin plastic.
