Editorial Review
The ball comes alive with forces, furiously thrashing and jerking as your arm and wrist try to keep it in control, spinning it faster and faster until you have it up to almost 15,000rpm and it's exerting about 40lbs of pressure on your limbs at a speed of 250 revolutions per second - no batteries, just pure gyroscopic power - the fastest human propelled device ever created! This is a great Product for all types of martial arts especially Judo where hands on grip is required!!!
