I have this key for some months now and I do not recommend. The price / GB is excellent at first, as its ergonomics. By cons, reliability is catastrophic. Already the mechanical strength of the case appears to be limited: the catch for indexing the extended position seems fragile; so the case had a crack from the day of purchase, it was perhaps in the package or it has formed quickly while I'm more kind of careful with my stuff. But the worst thing is the annoying tendency of this key corrompes files and folders it stores. The only way to delete these files is then format it. Unfortunately formatting if it deletes the corrupted files-folders, do not solve the problem and keep the key corrompes random files that are stored there.
