X2F CrazyLight – Pulsar Lab’s Radical Fingertip Mouse, Now Lighter Than Ever Designed and engineered by Pulsar Lab, the X2F CrazyLight takes its radical fingertip-focused design even further with an ultra-lightweight 29g ±2g construction. By removing the rear section of a traditional mouse, its reduced symmetrical shape enables quicker, more agile movement with less effort, making it ideal for players who demand speed and precise fingertip control. Powered by the flagship XS-2 sensor with up to 42,000 DPI and 8K polling rate support, the X2F CrazyLight brings speed, precision, and freedom of movement together in its lightest form yet.
