FOR MORE THAN 14 YEARS WE'VE HELPED ATHLETES, TRAINERS, AND RSI SUFFERES<br /><br />The original gyroscopic workout was conceived by Steven Chuang of Nano-Second Technologies. The original patent for the design was filed with the U.S. Patent office back in 1997.<br /><br />And as Nano-Second Technologies continues to improve and evolve the original design, countless numbers of golfers, ball players, athletes of every kind benefited from the improved strength and control over their forearms and wrists. Eventually, as the growth of the personal computer increased our daily use of the mouse and keyboards, millions of suffers of repetitive stress injuries and Carpal Tunnel Syndromes found solace with a few minutes of exercise on an Original NSD Spinner.<br /><br />With DECADES of research and development, NSD Power is the only manufacturer of these gyroscopic exercise machines you should TRUST.<br /><br />With various poorly engineered and constructed competitors out on the market right now, why take a chance with the quality, durability, and innovative design? NSD Power is the ONLY official distributor of NSD Spinners in North America and the only place where you can get cutting-edge new designs like our AutoStart models, or our LED counter models, or new, soon to be released features not found on any other gyroscopic exercise balls?
