ABOUT DANIEL + MOUSECHECK
Built to replace mouse guesswork.
Hi, I’m Daniel Reeves—a peripheral hardware enthusiast and the developer behind MouseCheck.
WHY IT EXISTS
A mouse problem should end with evidence.
I built MouseCheck because button faults, changing wheel behavior and inconsistent movement samples are difficult to reason about from memory alone. A useful test should show what the browser received, apply a stated rule and tell you what to check next.
The problem I wanted to remove
Many mouse checks stop at a blinking button or a stream of event numbers. That proves that something happened, but it does not tell you whether the round was complete, what the result means or whether the browser can identify the hardware cause.
The product I wanted to use
A focused set of tools that starts quickly, needs no account or software installation, keeps the method visible and gives a direct result. The current tools are free to use in the browser.
WHAT IS HERE NOW
Each page answers a different mouse question.
The site separates tasks because a browser click event, a wheel-direction check, a movement sample and a sensitivity formula do not prove the same thing.
Buttons, wheel and movement
The complete mouse test, double-click test and scroll test turn browser events into named round results.
Movement sampling and response
The polling-rate test reports browser-observed movement samples. The latency guide separates browser response from hardware and click-to-display measurement.
DPI and sensitivity
The DPI guide helps identify the configured value. The sensitivity converter exposes cm/360, eDPI, rounding and correction math.
One controlled next check
The double-click and scroll guides use the observed result and symptom scope to choose a repeatable comparison without guessing an internal component failure.
WHO IT HELPS
Different users, the same need for a clear result.
MouseCheck is designed for anyone who needs to move from “something feels wrong” to an observation they can repeat and explain.
Competitive players
Check whether expected inputs reach the browser, compare a changed condition and carry a known hip-fire turn distance between supported profiles.
QA and support work
Run the same bounded task twice, retain the conditions and report what the page observed without turning it into an unsupported hardware diagnosis.
Everyday troubleshooting
Find out whether a click, wheel direction or movement signal appeared, then follow the relevant next check instead of replacing random settings.
HOW A RESULT IS BUILT
Observation first, conclusion second.
The full rules and formulas are published on How MouseCheck tests work. The essential limit stays beside each live result so you do not have to leave a test to interpret it.
The page receives the action or value required by that task.
Button role, direction, time window, profile or user-declared scope gives the input meaning.
The page shows the rule it met, missed or has not completed.
When the page cannot identify a cause, it changes one condition and repeats the task.
HONEST LIMITS
A browser can report signals. It cannot open the mouse.
I would rather state a narrow conclusion that the page supports than turn a clean round into a promise about the switch, encoder, sensor or USB device.
Results can support
- Whether named signals reached this tab during the tested round.
- Whether a completed round met the rule shown beside the result.
- Whether two controlled rounds changed after one condition changed.
- What the documented sensitivity formula returns from the values entered.
Results do not certify
- The internal physical condition of a switch, encoder or sensor.
- A hardware USB polling rate or complete click-to-display latency.
- A publisher-certified game constant, identical feel or optimal aim setting.
- That an intermittent fault cannot appear outside a clean round.
