Bin are now one week in possession of Spin Masters and must say that it really makes a lot of fun. It was intended as a gift for my nephew and now the whole family plays it. In the beginning it is very difficult to control the spin master but with a little patience and a little fingertips feel it works after all. However, I must say that you have to watch a lot When it tilts or fingers on the small propeller. Hurts a bit. For children without supervision no good toy otherwise extremely high fun factor.
