How to Test Your Mouse Online

This mouse tester works directly in your browser. No installation, no sign‑up, and no tracking. Use the steps below to run a full mouse test in minutes.

  1. Click left, right, and middle buttons and confirm each click appears in the log.
  2. Scroll up and down to verify smooth, consistent scroll wheel behavior.
  3. Press side buttons (if available) and check the button status indicators.
  4. Watch for double‑clicks or missed clicks that may indicate switch wear.

Common Mouse Issues & Fixes

If your results look inconsistent, try these quick fixes before replacing hardware.

  • Clean the scroll wheel and sensor area to remove dust buildup.
  • Test on a different surface or mouse pad to reduce tracking errors.
  • Update mouse drivers or reset software profiles.
  • Try another browser to rule out extension interference.

What your results mean

Double‑clicks detected

If a single click registers twice, your switch may be wearing out. This is common in older mice.

Missed clicks

If clicks fail to register, try another USB port or update drivers. Persistent misses suggest hardware faults.

Scroll wheel jumps

Jumping or reversing scroll direction can indicate dust in the wheel encoder or sensor degradation.

Hold test drops

If a click‑and‑hold releases unexpectedly, the switch may be unstable or failing.

Mouse diagnostic guide

Use this checklist to interpret your mouse test results and decide what to do next.

1) Confirm the basics

  • Try a different USB port or a powered hub.
  • Disable USB power saving in your OS settings.
  • Test without browser extensions enabled.

2) Check hardware symptoms

  • Double-clicks usually mean a worn switch.
  • Scroll jumps often point to a dirty encoder.
  • Missed clicks can be cable or switch issues.

3) Test on another device

  • If issues disappear, software may be the cause.
  • If issues persist, hardware repair may help.

4) Decide next steps

  • Clean sensors and update drivers first.
  • Replace switches if double-clicks persist.
  • Consider warranty replacement for new devices.

Advanced Tests

Mouse Sensor, Polling Rate, and DPI Testing

Explore additional mouse testing options to diagnose sensor accuracy, polling rate stability, and DPI behavior.

Mouse Sensor Test

Check for jitter, skipping, and sensor accuracy issues. A sensor test helps validate consistent tracking on different surfaces.

Mouse Polling Rate Test

Polling rate determines how often your mouse reports its position. Higher rates feel smoother and more responsive.

Mouse DPI Test

DPI affects cursor sensitivity. Use this tester to compare movement consistency and verify DPI settings.
