The cutting-edge laser tracking system permits ultimate experience – it works on almost every surface, including glass desk, lacquered desk, ice, and sofa. Take it anywhere you want to go, and feel the smooth motion.
Note: For better glass-tracking performance, glass thickness of at least 4mm is recommended. If you are using the brand new or extremely clean glass-surface, please leave it a while or swipe the glass with cloth before using this mouse. The dust particle will enhance the tracking performance.
