What Is a Mouse Tester?
A mouse tester is a free online tool that helps you check whether your left click, right click, middle click, and scroll wheel are working properly.
When you press any button, the tool shows a visual response — so you can instantly confirm if your mouse is in good condition.
How to Use the Mouse Tester
Follow these simple steps:
- Open the Mouse Tester Tool on your screen.
- Click the left, right, and middle buttons — each click should be highlighted.
- Scroll up and down to test your mouse wheel.
- Move your mouse around — the cursor movement should be smooth.
- If a button doesn’t respond, try changing the USB port or reconnecting the mouse.
Why Use This Tool?
- Detects unresponsive or double-clicking buttons.
- Tests mouse scroll wheel and pointer movement.
- Useful for checking new or old mice before buying or using.
- No download or setup — just open and test!
- Works on Windows, Mac, and mobile browsers.
Tips for Better Results
- Clean the bottom sensor area before testing.
- Use a flat surface for accurate pointer movement.
