Mouse Test Online
Check if all your mouse buttons are working properly. ProbeCheck detects left, right, middle, and side button clicks, tracks scroll wheel direction, measures cursor jitter (unwanted micro-movements when the mouse is still), and estimates your mouse polling rate.

Clicks and scroll detected accurately. Polling rate estimated from pointermove intervals.
Frequently Asked Questions
How do I test if my mouse buttons are working?
Click each button on your mouse (left, right, middle/scroll, and any side buttons). The test area will highlight each button as it's pressed, helping you identify any non-responsive buttons.
What is mouse jitter and how do I test it?
Mouse jitter measures unwanted cursor micro-movements when you try to hold the mouse still. High jitter (above 1-2 px) can indicate a faulty sensor, poor surface, or wireless interference. The test analyzes pointer movement variance during normal use to estimate jitter stability.
What is mouse polling rate and why does it matter?
Polling rate is how often your mouse reports its position to the computer (measured in Hz). Higher rates (1000Hz) mean more responsive cursor movement, which is important for gaming and precision work.
Why isn't my mouse side button detected?
Some mouse side buttons are mapped to browser functions (like forward/back) and may not register as standard mouse buttons. Try testing in a different browser or check your mouse driver software.
