Mouse Tester

Diagnose a flaky mouse before you blame your reflexes. This tool tests left, right, and middle clicks, checks for double-click issues (a common sign of a worn-out switch), tracks scroll wheel input, and can estimate polling rate and DPI from your cursor movement. Move, click, and scroll to see live feedback on every input — useful for testing a new mouse, troubleshooting an old one, or checking whether 'click' registration lag is actually a hardware problem.

Diagnose Switch Faults, Scroll Issues, and Polling Rates

Mouse hardware issues—such as double-clicking switches, missed clicks, erratic scroll wheels, or irregular polling rates—can ruin gaming performance and daily productivity. Isolating hardware faults from software lag requires precise, real-time input tracking.

The Mouse Tester captures and measures every physical action your mouse performs, providing instant visual feedback on click accuracy, scroll steps, and sensor responsiveness.

Key Features

  • Multi-Button & Side-Click Testing: Verify input registration for left, right, middle (scroll click), and side navigation buttons (Mouse 4 and Mouse 5).
  • Automatic Double-Click Detection: Flag worn-out microswitches by tracking unexpected fast-consecutive click events (often measured in milliseconds) that indicate hardware switch bounce faults.
  • Scroll Wheel Direction & Speed Tracking: Measure vertical and horizontal scroll wheel steps, detecting skipping or reversed scrolling inputs.
  • Polling Rate & Sensor Monitor: Estimate your mouse's reporting rate (Hz) and track smooth cursor movements to verify sensor stability and prevent input jitter.
  • Drag & Hold Test: Test continuous click retention to identify switches that drop inputs mid-drag during click-and-drag operations.

Common Use Cases

  • Switch Health Audit: Confirm whether a double-click issue is caused by a failing physical microswitch or mistaken double-click speed settings in your OS.
  • Gaming Hardware Setup: Verify that high polling rate settings (e.g., 1000Hz or higher) register accurately without dropping packets or overloading CPU threads.
  • New Device Inspection: Test fresh or newly unboxed gaming and ergonomic mice before your return or warranty window closes.
