Mouse Tester

About This Mouse Button Tester

This user-friendly online tool works with both standard office mice and gaming mice. It detects left, right, middle, two side buttons, as well as upward and downward scroll wheel movements. The page features an integrated test zone: click statistics display on the left, while a realistic mouse graphic on the right shows real-time button feedback, allowing you to quickly identify dead or unresponsive mouse keys.

How to Use

1. Move your mouse inside the unified test zone marked with a plus sign to begin testing.
2. Press any mouse button; the matching area on the mouse graphic will light up, and the click counter on the left will update simultaneously.
3. Scroll the wheel up or down, and corresponding directional arrows will appear temporarily on the graphic before fading out automatically.
4. Side button presses are fully detected and logged to the counter panel.
5. Hit the "Reset All Stats" button to clear all counts and restart your test session.

Key Advantages

1. No complicated setup required — just hover into the test area to get started.
2. Intuitive visual mouse diagram provides instant feedback for every button and scroll input.
3. Precise click counting; holding a button will not add repeated counts for accurate statistics.
4. Isolated test zone blocks unwanted browser behaviors including page scrolling, right-click menus, and back/forward navigation via side keys.
5. Compatible with nearly all mainstream office and multi-button gaming mice available on the market.
6. Scroll indicator arrows automatically hide when idle for a clean, uncluttered interface.
