Query: Excellent so far!!!

This flash drive is amazing. Works like a charm with XP, and will work with or without the case that the other reviewer had problems with. It comes with a carrying case about as thick as three credit cards (still very thin for a flash drive) that holds two of these drives, and fits nicely in your wallet.Again, the case isn't required to use this drive. Without the case, you can still plug the CARD ITSELF into your USB.Highly recommended!!
