I got one... Don't expect too much (like for it to work well) like I did.
The device has A LOT of problems pairing with the phone. There are a ton of bad reviews for the pairing app about not being able to pair the device on multiple phones. I was able to pair mine and play a couple games, once I disconnected it I have been unable to pair it again. Here is the pairing app to read the reviews yourself: https://play.google.com/store/apps/details?id=com.bda.pivot.mogapgp
If they could fix this it would be fantastic. Works really well for the games that are optimized for it (I played TDKR and PAC MAN). Hopefully they fix it soon, if not I'll be returning mine.
