ERGONOMIC VERTICAL MOUSE: Designed by leading physiotherapists in the UK, the DXT was engineered to promote a neutral, more vertical wrist posture while allowing the hand to work with a light touch fingertip hold providing precision cursor control. CONVENIENT AND RELIABLE WIRELESS CONNECTION: Connect the compact RF dongle to an available USB port on your computer for quick and easy pairing. FINGER TIP GRIP INCREASES PRECISION: Unlike other vertical mice, the DXT 2 is held like a pen in the “precision” grip which engages the small muscles and joints of the fingers as opposed to large muscle groups of the shoulder. IDEAL FOR RIGHT AND LEFT HANDERS: Switch instantly between right and left handed use with the tap of a button. No changes to button-assignments in the operating system are required. AMAZING BATTERY LIFE AND CHARGING PERFORMANCE: The integrated, rechargeable lithium-ion is engineered to last for 2 weeks on a full charge, and the rapid charge system allows 2+ hours of use with a mere 30 seconds of charging.
