NSD powerball - wrist and arm streangthener

This revolutionary device uses gyroscopic technology to resist the motion applied to it! It is used by musicians, sportsman (the man with one of the longest golf drives in the world uses it), physios and people looking for something to blow their friends away!

It is the fastest spinning non motorised device in the world reaching speds of up to 15000 RPM! And this all comes from a simple wrist motion that builds rock hard forearms, a steel grip and wrist and elbow streangth worthy of a body builder you can really feel it working!

The computer allows you to measure top speed, current speed and has endurance modes. The faster you spin the brighter the lights shine! it looks like a disco ball gone crazy and around a  fire with mates the adrenaline will really get pumping to reach that high score.

Incuded is a starting string, instructions, the powerball (with amber lights) and the computer which is attached (as seen on pic). Other cheaper models are available however this has all the bells and whistles. visit www.nsdpowerballs.com for videos!
