Common Mouse Problems
Ghost Clicks / Double Click Issue
If your mouse registers two clicks when you only click once, the microswitch inside is likely worn out. This is the most common mouse failure and is especially prevalent in mice over 2 years old. Use the ghost click detector to confirm the issue.
Scroll Wheel Problems
Scroll wheels can skip lines, reverse direction, or stop working entirely. The scroll wheel test helps you verify whether the issue is hardware or software related.
DPI / Sensitivity Issues
If your cursor moves too fast or too slow, your DPI settings might be off. Use the DPI tester to measure your mouse’s actual sensitivity.
