Neon Green 'Pro' contains the same perfectly balanced rotor as found in the 250Hz model range but with the addition of 6 ultra intense LED's which glow brightly when the gyro is activated. Naturally, the faster you spin, the brighter the LED's glow until your whole hand is engulfed in an almost surreal [alien] like envelope of light!
