Review: So cool - My goalie son got a concussion and was really suffering with delayed reactions which is not ideal when a puck is flying at you. This has really helped him reconnect those muscles and eye coordination. He can do it himself against a wall or I bounce it to him. It keeps his interest long enough to make a difference.
Review: Very Versatile - My trainer recommended this ball and it's so much fun! You do need a wall that you can bounce it off it. Great for brain work, coordination and balance depending on how your use it. I use it my garage because I get a good bounce off the wall and the floor. Just make sure, your car is not in the way!
