It allows you to change the sensitivity of the mouse’s pointer speed (1000 / 1600) with one press. You can make it slower for things that require precision, like photo edits, or make it faster for browsing.

It provides great convenience when you browse the web page. Just click the forward or back buttons to switch to the previous or next page you watched before.
Comfortable Thumb Rest
Features a comfortable thumb rest designed to reduce strain and enhance your grip during extended use. Help to build a natural hand positioning, ensuring optimal comfort and precision.
