[Small Ergonomic Mouse] Measures 11.44 x 6.7 x 5.8 cm. It's smaller than a typical ergonomic mouse, making it suitable for Japanese users with small hands. If you find the PERIMICE-508/608/513/713 too large, try this mouse. [Ergonomic Design] The vertical ergonomic design fits snugly in your hand and keeps your wrist and arm in a natural position. Recommended for those who work long hours on a computer or suffer from wrist pain. The surface is rubber-coated to prevent grip slippage. [Rechargeable] Powered by a Li-Po (300mAh) battery. Rechargeable, eliminating the need for a battery. Up to 15 days of continuous use (based on 4 hours of use per day). It automatically enters sleep mode when not in use to conserve power. It wakes up when you move the mouse after sleep. [Quiet and Energy-Saving Design] This quiet mouse is easy to use even in places where clicking noise is a concern. [Convenient Features] Equipped with 6 buttons, including side buttons for browsers' "Back" and "Forward" functions. Uses an optical sensor. The center button controls cursor movement speed in three different settings (DPI: 1000 / 1600 / 2400). Compatible with Windows 10/11, Linux Ubuntu 16.04, Chromebook, iPadOS, Android, and Amazon Fire Tablet. (The back and forward buttons may not work on MacOS.)
