Techno NSD Powerball is the very latest addition to the exciting family of NSD Powerball products!This innovative gyroscope scrolls your achieved score 'magically' across the surface of the rotor (as opposed to displaying it instantly on a digital speed meter as with the other models in the range).The rotor also displays an entrancing collection of 'firelines' as it spins, ranging from red to blue in colour and giving an a truly amazing effect depending on the speed at which it is revolving.
