Disclaimer
This page is straightforward. It tells you what Mouse Tester is, what it is not, and where the limits of the tool sit. Nothing here is written to protect us from imaginary lawsuits; it is written because honest limits are more useful to you than false confidence.
If you have a question after reading this, the contact address is at the bottom.
What This Tool Actually Does
Mouse Tester reads the input events your browser receives from your operating system. When you click a button, scroll the wheel, or press a side button, the operating system sends a signal to the browser, and the browser forwards that signal to the tool. That is all that happens.
The tool does not communicate with your mouse hardware directly. It does not access firmware, drivers, or any part of your system outside the browser window. It sees exactly what your browser sees, no more, no less.
That matters when you are reading results. A clean result means the signal reached your browser cleanly. It does not mean the hardware is in perfect condition at every level. A fault sitting below the browser layer — in the driver, the firmware, or the physical switch may not surface in a browser test.
Test Results Are Not a Certified Hardware Diagnosis
What the Results Tell You
When a button lights up green, and the counter reads 1 from a single press, it means your browser received exactly one click event. When the scroll wheel registers one event per notch, it means the encoder is sending clean signals to your operating system.
These are useful, reliable facts. For the most common mouse problems, double-clicking, scroll wheel misfires, and unresponsive side buttons, the results are accurate enough to point you in the right direction.
What the Results Do Not Tell You
The results do not tell you:
- Whether your mouse switch is near the end of its lifespan, but is still functional
- Whether your firmware has an issue that only shows up in specific software
- Whether intermittent faults will reproduce during a short test session
- Whether the problem is happening above the browser layer, such as inside a game engine or application
An intermittent fault is the hardest thing to catch. A switch that double-clicks randomly once every fifty presses may not produce that fault during your two-minute test session. If the problem you are experiencing is occasional rather than consistent, a clean result here does not rule out a real fault; it just means it did not show up during this session.
Decisions Based on Test Results Are Yours to Make
If you use the results from this tool to decide whether to repair, replace, or keep using your mouse, that is a decision you are making for yourself. The tool gives you information. It does not make the call for you, and we are not responsible for the outcome of choices made based on what you saw here.
This is not a disclaimer written to dodge responsibility. It is a plain acknowledgment that a browser tool has real limits, and the decision to act on its output is always yours.
Supporting Content and Accuracy
Articles and Guides on This Site
The pages on Mouse Tester that explain how to interpret results, what common faults look like, and how different mouse specs affect performance are written in good faith based on available information. We update them when something changes or when better information becomes available.
That said, hardware behavior varies. What is true for one mouse model or driver version may not hold exactly for another. The explanations on this site are general guidance, not manufacturer specifications or certified technical documentation.
Benchmark Figures
Where we publish benchmark ranges, for example, typical jitter values by mouse tier or polling rate accuracy thresholds, those figures are drawn from testing and community data. They are reasonable reference points, not laboratory measurements. Your specific result may fall outside those ranges for reasons unrelated to a fault.
External Links and Third-Party Tools
Some pages on this site link to external resources, tools, forum threads, hardware documentation, or community discussions. Those links exist because the content is useful. We do not control those sites, cannot guarantee their accuracy, and linking to them does not mean we endorse everything on them.
If an external link stops working or the content behind it changes, the information on Mouse Tester may temporarily be out of step with what you find there. We check links periodically, but cannot monitor every external resource in real time.
Advertising
Mouse Tester is free and supported by ads. Ads on this site are served through Google AdSense. We do not control which ads appear, and an ad appearing on this site is not an endorsement of the product or service it promotes.
If you see an ad that seems misleading, harmful, or inappropriate, report it to Google. You are also welcome to let us know, contact details below.
How advertising data is handled is covered in the privacy policy, which explains what Google AdSense collects, how it works, and how to opt out of personalized ads if you prefer.
No Warranty
Mouse Tester is provided free of charge, as-is. We do not offer any warranty, express or implied, that the tool will work in every browser version, with every mouse model, or in every operating system configuration.
The tool has been tested across common environments and works reliably in modern browsers. But if your setup produces an unexpected result, the cause may be a browser quirk, a driver version, an OS setting, or a hardware configuration we have not encountered. A result that looks wrong may be worth investigating further before acting on it.
Changes to This Disclaimer
We may update this page when something changes about how the site works or what it covers. The date at the top reflects the most recent revision. Continuing to use Mouse Tester after an update means you accept the current version of this disclaimer.
