Left Click Test
Verify your left mouse button and measure its speed.
Your verdict appears here
70
Gaps shorter than 70ms get flagged
How it works
- 01
The left button takes the most wear of any switch on a mouse, so it fails first. Check mode confirms every press arrives.
- 02
Speed mode runs the standard timed CPS window.
- 03
The trace flags gaps under 70ms, so a bouncing left switch shows up here as well.
Common questions
Why does my left click sometimes not register?
A worn switch can miss presses as well as duplicate them. If light presses fail but firm presses work, the contact has lost tension.
How many clicks should a mouse survive?
Most switches are rated for 10 to 50 million presses. Heavy gaming can reach that inside a couple of years on the left button.
