Leap Motion is a really super cool item !! there are really only 2 criticisms: 1. The price: The price at Amazon is way too expensive !!! on the manufacturer's site you get the part 90 and $ 99.99 at Amazon it costs 2. The Leap Motion works per se, but with clamps movements they can not get to what, according to that has it is completely confused and you take your hands off and will have to mouse over a resist new (is really annoying with time and effort)
