Mouse Button Tester

What is the Mouse Button Tester?

The Mouse Button Tester lets you verify that every button on your mouse — left, right, middle, side buttons (M4/M5) — is registering correctly. It helps diagnose hardware issues like unresponsive buttons, double-clicking, or stuck switches.

Why Test Your Input Devices?

Hardware issues are often mistaken for software problems. Before troubleshooting drivers or game settings, use these diagnostic tools to verify your physical hardware is functioning correctly. A faulty mouse switch or worn encoder can silently sabotage your gaming performance.

Why Test Your Input Devices?

Test your devices when you notice inconsistent clicking, unexpected double-clicks, cursor drift, or scroll wheel skipping. Regular testing also helps track hardware degradation over time.
