This limited edition gyroscope has a top speed in excess of 16,000rpm and can generate over 18kg of resistance on the hands and arms as it spins (which is quite extraordinary given that it is just the size of a tennis ball and weighs under 300grams!).

The new Signature is our Premium Neon Powerball model and is supplied with full operating instructions, 2 starter cords, a hand strap, and an exclusive mini DVD providing you with exercise routines, three exciting Powerball film clips, starting tutorials plus the full suite of Akis World Speed records to really spin your mind!
