TECKNET Ergonomic Mouse, 4800 DPI Wireless Vertical Mouse with 5 Adjustable DPI Levels, 2.4GHz Optical Carpal Tunnel Mouse, 6 Buttons Wireless Mouse for Laptop, Desktop, PC, MacBook - Black

ARM PROTECTION: The ergonomic vertical mouse allows you to adjust your arm and wrist to a comfortable position, reducing arm muscle tension for more comfortable movement and less stress.
PRECISE CONTROL: The ergonomic mouse uses an optical sensor with 4800/3200/2400/1600/800 DPI, providing higher sensitivity than standard optical mice, allowing smooth and precise tracking on a variety of surfaces.
QUIET DESIGN: Say goodbye to loud clicking sounds and welcome to a quieter environment. The vertical wireless mouse adopts a silent clicking design, and the clicking noise is reduced by more than 90%, thereby avoiding disturbing others and ensuring that your work or study will not be interrupted.
RECOMMENDED BUTTONS: The forward/back buttons of the carpal tunnel mouse will help you greatly improve your work efficiency when browsing websites/reading emails, which is very suitable for web surfers, gamers and people who work long hours (Note: The side buttons are not suitable for Mac or IOS systems)
ENERGY SAVING: The laptop wireless mouse enters sleep mode (completely cuts off power) after 8 minutes of inactivity, press the left or right button to wake it up.
Note: We recommend using branded batteries to ensure the working life of the mouse. When the battery is low, an LED light will flash. (2 X AAA batteries not included)
