Popped it into a Surface laptop/tablet. It worked straight way.Little card has a big memory by today's standards. But in the morrow of the future it won't bemuch space. For now, this is the maximum space for a MicroSDHC card. There ain't no card bigger than this. There ain't no 128 or 256 Gbs MicroSDHC card.Good deal. Fast arrival.What more can I write.
