The design of NSD Power® products is protected under more than 100 patents worldwide. 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.

With DECADES of research and development, NSD Power is the only manufacturer of these gyroscopic exercise machines you should TRUST.

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?

Do not buy anything from this seller!

I purchased a gyro wrist spinner that is totally useless. Poor quality, doesn't work, & they refuse to take back.

You would receive more benefit from giving your money to a homeless person than buying anything from this company!

Rating + 3 Good seller - poor product

The item was promptly shipped and received in good condition. The product is very difficult to use and so far, useless to me.
