Title: Dont buy from reseller
Review: I bought one from the used and new section and bought a counterfeit 2gb MS DUO, it came boxed originally and everything and when I tried using it with my PSP, it kinda worked. Data will be corrupted when its written in, and it will be recognized sometimes only. There are a lot of these counterfiet MS out there, you might want to only buy from actual stores.
