The Anker Wireless Vertical Mouse’s performance is decent. It isn’t designed to be as performant as gaming mice and its sensor is noticeably inferior when compared to such mice. It only has 3 CPI settings of 800-1200-1600. Its sensor is quite inconsistent and sensitivity seems to change when using the mouse. The lift off distance is also very high and you can’t adjust its polling rate.
Note: We usually do these tests at 1000CPI, but had to test this mouse at 1200CPI since it doesn’t have software allowing for CPI customization.
