When Aerodrums came out, the concept was nice, but the use of a light in the face (Playstation 3 eye camera) to get it to work was a massive turnoff, so I let that one fall by the wayside. Since then, a KickStarter page popped up (now expired) to fund a competitor (Freedrum) that works on sheer motion, so is truly mobile. The first batch of that just sold out, and they are getting the second batch in 4 weeks (just got an email on this last week).
 
Has anyone tried these out, and the real kicker... anyone stress-tested these on an Android phone?
 
(My computer does not have BT4.0, and although the above list supports older phones than mine, the information about Android usage is rather sparse.)
