What is the Mouse Tester & Polling Rate Test?
Click, scroll and move inside the test box and each part of your mouse lights up as it is detected: left, middle, right, and the back and forward side buttons, plus wheel notches up and down. It counts clicks, shows your pointer position and speed, and helps you spot a worn or faulty mouse.
Two diagnostics set it apart. The double-click bug check flags a single physical click that registers twice within 50 milliseconds, the classic symptom of a worn micro-switch. The polling-rate test measures how often your mouse reports its position — 125 Hz for basic mice, 500 to 1000 Hz for gaming mice — from the time between movement events while you move the mouse quickly.

Questions people ask
What is mouse polling rate?
How many times per second the mouse reports its position. 125 Hz = every 8 ms, 1000 Hz = every 1 ms.
What is the double-click bug?
A worn switch registers one press as two clicks, causing accidental double-clicks and broken drags.
Why is my measured rate lower than advertised?
The browser merges events, and the rate depends on movement speed and your operating system. Move fast, and use a wired connection.
Do the side buttons work?
Yes, back and forward buttons are detected when your mouse has them.
Can I test a trackpad?
Yes, though trackpads have no side buttons and different polling.
