4.5 Amazing piece of work!!! TennisChris | 08/02/2011 | See all TennisChris's reviews (7) This is one of those things that you think if its worth buying because your not sure if its going to work. But I went ahead and bought it and boy does it work. We went on holiday with it and just couldnt leave it alone. It definately works and when thrown properly bounces along the surface at a far distance. The best use for it would be in the sea. Great fun, definately worth buying!!!!!!!!!!!
