I bought a few months ago the stick. The locking is very shaky, but it can get used to. Unfortunately, I have already repeatedly had the problem that the stick is suddenly appears (under Windows 7) as unformatted. He can do through reformatting or by Transcend online recovery tool usable again but the data are gone. I'm using it now just to quickly transfer data in the same room time - for the storage of data it is too unreliable.
