I really, really like mine. It's one of my favourite things of having a "next gen" console, first party wireless mm. I tend to play in all sorts of weird positions and hold my controller at odd angles like above & behind my head, so it's awesome not tangling myself in wires.
Back when I had a camera and I played Uno a lot, I never saw anyone doing weird/naughty stuff with it. I got rid of mine when I lost my good connection, but I kind of wish I still had it so I could use it to make custom characters with crazy faces in like Vegas 2 and such. Plus Totemball is the best freakin' game since Yaris.
