RolerBall reviews

This transparent ball, which has a three-metre diameter, is made from very tough material and has two skins into which air will be inflated (by means of a powerful pump that you get together with the ball and will help you inflate it in no more than a quarter of an hour). The ball contains two internal harnesses to which one or two participants will be strapped. Once you have secured yourself in with the straps, you can launch down a slope and feel the excitement this mad device has in store for you.
