How It Works
1
Click on interactive mouse diagram
Test Left (LMB), Right (RMB), Middle (Scroll Wheel), and side auxiliary buttons.
2
Audit switch chatter & double clicks
Debounce analyzer flags microswitch chatter and abnormal secondary clicks under 80ms.
3
Check scroll encoder and test CPS
Rotate the scroll wheel to audit encoder anomalies and complete the 5s CPS speed challenge.
Frequently Asked Questions (FAQ)
What is mouse double-clicking and how is it detected?
Double-click flaws occur when worn microswitch contacts chatter. The detector alerts in red if debounce fails.
How do I test scroll wheel stability?
Spin the wheel in the scroll test container: reverse twitches highlight failing optical/mechanical encoders.
What is a typical CPS (Clicks Per Second) score?
Average users click at 6-9 CPS, while competitive esports players achieve 12-16 CPS with jitter clicking.
