I have several thumb drives. The PNY thumb drive case slips off very easilt, the cover is too easy to lose, there is no lanyard and worst of all it is so flimsy that just inserting or removing it into a USB port is likely to break the end right off. None of the others I have seem so fragile which is contrary to what they are supposed to be designed for.8 GB and ReadyBoost is what I wanted but I should have stuck with brands I trust.
