Frequently Asked Questions

Why is my mouse double clicking automatically?

If you click once but your computer registers two clicks, your mouse likely has a failing microswitch. This is very common in older or heavily used gaming mice. Use the test zone above to verify if your mouse is registering ghost clicks.

How can I test if my scroll wheel works?

Simply hover your cursor over the large testing area on this page and scroll up or down. If the "Pixels Moved" counter goes up and the direction is accurately recorded, your sensor is working perfectly.

What is a good CPS (Clicks Per Second) score?

An average internet user typically scores around 6 to 8 clicks per second. However, competitive gamers (especially in games like Minecraft) use techniques like jitter clicking or butterfly clicking to achieve speeds of 10 to 14+ CPS.
