V.Smile Motion Wireless Controller

My 10 year old son is Autistic and because of this he's quite a fidget with his hands when he's getting excited, which I have to say he does lots while playing on his V.Smile Motion he absolutely adores it!! However he does get quite frustrated as while he's finger fidgeting because of the positioning of the power button being so close to the edge of the controller his positive praise and enjoyment of the game cuts off as he's switched the controller by accident. If that button could be moved more central to the controller it'd be ideal! It's really helped both him and his little brother (who is 4) with their hand to eye coordination!! They love the fact that they're having to move themselves to be in control of the characters where as if it was just a normal controller they get bored as they're not moving anything other than their fingers!! Brilliant product - just need to shift that button!!
