Excellent memory accessory.
Im very pleased with my VMU. It has the standard 128 units and 8-bit black and white LCD screen perfect for playing mini-games from from titles like Power Stone and Sonic Adventure.

Yes it works...
...with US consoles as well. I'm glad I was able to get a controller for this low price. It is new in package, and it works with saving games. I already got Lost Hope saved, a game which I've ordered from this site as well.

Memory card, and a bunch of other functions
No, this is not as useful as a swiss army knife, but this is one of the BEST and the most creative memory card ever invented for a game console.
Not just a way to store saved games and game data, but also for mini games. too bad not that many vmu games are created. but fortunately, you can find home-brew vmu games on the internet.

Wow
Still the most intuitive memory card out there. I was lucky enough to get a DreamCast recently with Shenmue and Sonic Adventure and while playing Shenmue I was delighted to find that the VMU displayed the keys I had to press to learn a new move. Truly great. =D

Happy and upset
I was very pleased with the fast shipping. When I received the vmu, the battery was dead.
