I've had a wavebird for a while now and have to say i'm not too impressed with it.
Far too many times it skips a beat and in a game like mario etc thats crucial.
Its not too bad when I'm in the same room as the cube but I was led to beleive it would work from any room in the house and when using it one room away from the cube it starts to get a bit tetchy!
Anyone else notice any problems? Probably not as most will be using it in the same room as the cube i guess?
