Mouse Double Click Test
Click the left button normally, one click at a time. If your mouse sends two clicks for a single press, the test catches it and shows exactly how many milliseconds apart they were.

Event log
How to check your mouse for double clicking
- Keep the pointer inside the test area and click the left button at a normal pace — not as fast as you can.
- Do at least 30 clicks. Faulty switches often fail only once every 10 to 50 presses, so a few clicks are not enough.
- Watch the “double clicks” counter and the red lines in the event log. Each one shows how many milliseconds passed between the two presses.
- Repeat with the right button and the side buttons — any switch can wear out.
Reading the result
No red entries after 30 or more normal clicks means the switch is healthy. One or two flagged presses with gaps of 50–80 ms can simply be a very quick finger, so lower the threshold and try again. Repeated gaps under 30 ms are a clear sign of a failing switch, especially if they happen while you click slowly.
Why mice start double clicking
Most mice use small mechanical micro switches. Every click scrapes the contacts a little, and after millions of presses — or sooner with humidity and dust — they stop making a clean contact. Mice with optical switches do not have this problem, which is one reason many gaming mice now use them.
Not a hardware problem?
Check that the double-click speed in your operating system settings is not set extremely slow, and that no macro or rapid-fire setting is active in your mouse software. Then test every button and the wheel with the full mouse test.
