Loaded with a high performance 250Hz rotor, Neon models have an added feature of 6 inbuilt ultrabrite LEDs which glow brightly once the NSD Power®Ball is spinning.
There are no batteries required (other than those for the counter) - that surreal glow which engulfs your hand during use is generated by a small induction coil also present on the rotor - the faster you spin, the brighter it glows!
All Neon balls are available with an inbuilt digital counter (termed: Neon Pro) or without (termed: Neon Classic)
Best of all, the Neons are ultra desirable - just take a look at that delicious image of the Neon Green Pro in action! In fact, with a single glance, you'll be hooked.. who wouldn't want one..
