don't buy those no name brand of usb sticks. I bought a no name brand once (was good price only if was working) but the stick always got stuck a 1gb, even though it was a 8gb stick. After initial 1gb of files I stuck on it, rest would just be saved as garbled junk that wouldn't open or are invalid files.
And it was new too, or at least it was still in the plastic retail box that I had to cut open to get the product out.
