Scope of the tools
The site provides free browser input observations and an estimated mouse DPI measurement. Results depend on browser delivery, system settings, device behavior and your test technique. They do not guarantee hardware performance or identify an exact failure.
Troubleshooting decisions
Follow your manufacturer’s instructions for cleaning, drivers, warranty and repair. Do not open, modify or replace equipment solely because of one browser score. Compare another application or computer when possible.
Availability and saved results
The tools are provided as available without a paid service contract. Browser storage can be cleared or unavailable, so keep an exported result when it matters to you. No registered account or server-backed result recovery is offered.
External resources
Documentation links are provided to explain input methods and safe basic troubleshooting. Their content and terms are controlled by their publishers. No active affiliate, advertising or sponsored recommendation program is included.
