Bought this USB a couple of years ago, never had any trouble with it corrupting, etc. and the lid snaps onto the other end of it, which is useful if you think you might lose the lid. Highly recommend it although a 4/8GB one might be more useful, 2GB can get used up quickly
Only criticism is that the metal part that plugs into the USB slot has started to come loose, but I use it multiple times every day so I guess that's just general wear-and-tear, and it still works perfectly
