Mouse Test

Test mouse buttons, wheel, double-click and chatter (misfiring clicks) in your browser.

Click every button and scroll the wheel to check that your mouse works. Each part of the mouse lights up as you test it.

Chatter check: if a single click registers twice within 50ms, the switch may be failing (double-click chatter). Genuine double-clicks are slower than that.

Buttons tested: 0/5
Last button: —
Click interval: —
Scroll ticks: 0

✓ No chatter detected — clean clicks

About This Content

Free online mouse test to check your mouse in seconds. Click the left, right, middle and side buttons and scroll the wheel — each part lights up as you test it. It measures the interval between clicks in milliseconds to detect chatter (when one click registers twice because a switch is failing) and checks scroll direction and ticks. Everything runs right in the browser — no download, no install. Perfect for diagnosing a double-clicking mouse or checking a new one.
