Query: Doesn't work - On any System

Bought this as a birthday gift for my son.Doesn't work. Was waiting a long time for this gift and it was DOA.Locked up my computer. Didn't work on his either.Called their support line which they did answer fast, but after trying this and that he said it has a bad memory card.I WANT MY MONEY BACK!Don't get stuck in the Nextar quality hole!
