Scroll Wheel Test
A scroll wheel click test checks how smoothly your mouse wheel scrolls and how well the wheel button clicks, both of which wear out over time on heavily used mice. Use this scroll click test to confirm your scroll input is registering evenly, with no skipped notches or double-scroll jumps.
How the Scroll Wheel Test Works
Scroll up or down inside the box to register input for this scroll wheel click test. Every detected scroll notch counts toward your total, letting you check for consistency across the wheel's full range of motion.
Spotting Scroll Wheel Wear
If your scroll click test results feel uneven, with some scrolls registering multiple steps and others none, your scroll wheel mechanism may be due for cleaning or replacement.
