We have given this ball game for our son's fourth birthday. We have built it inside, using an umbrella stand. But of course you need a big room, so that the ball can fly with us fits in the big kids. He needed a little practice, but from the first minute he had so much fun. The 7-year brother also plays for hours alone. Also together and against each other to find the kids loved it. If the children have left home, the adults sneak to the device. Flying Balls - tamed on a string - really great fun! We will take it in any case in the camping holiday and also give it away again!
