How to test your mouse
01
Click each button
02
Roll the scroll wheel
Scroll up and down over the mouse diagram. The arrows confirm each encoder step — skipped or reversed steps point to a dirty or worn encoder.
03
Watch the interval
The "Last Interval" reading shows the milliseconds between clicks. Anything under 50 ms from a single press is flagged as a suspected switch fault automatically.
04
Check polling rate
Move the cursor quickly inside the test area in circles. The live Hz reading approximates your mouse's polling rate — 125, 500, 1000 Hz or higher.

How Do I Test the Middle Mouse Button?
Press the scroll wheel as a button and check the Middle Click [MB] field. Each successful press and release should be registered by the tester.

Why Use a Mouse Button Test
A mouse button test checks whether the main buttons, side buttons, and scroll wheel register presses and releases correctly. It’s useful when a button sometimes fails to respond, registers one press twice, or produces inconsistent click intervals. The tool records each action and can flag a suspected double-click fault when a single press is registered twice within 50 ms. It also shows click timing, total presses, rapid clicks, pointer position, and recent input history, which makes it easier to identify whether the problem comes from a specific mouse button.
How to Use
Click each mouse button several times and use the scroll wheel in both directions. The corresponding field shows each press and release, while the statistics below record click intervals, total presses, double clicks, rapid clicks, and other detected inputs. If a single physical press is registered twice within 50 ms, the tool marks it as a suspected double-click fault. The action history at the bottom can be used to compare individual inputs and their timing.
