Also, sometimes you just want to verify if all buttons work on a new or old mouse.</p> <p>Link:<br> </p> <div class="crayons-card c-embed text-styles text-styles--secondary"> <div class="c-embed__content"> <div class="c-embed__body flex items-center justify-between"> <a href="https://starryring.com/en/toolbox/" rel="noopener noreferrer" class="c-link fw-bold flex items-center"> <span class="mr-2">starryring.com</span> </a> </div> </div> </div> <p>Features in action:</p> <p>Visual mouse model that lights up when you click a button</p> <p>Clean dark theme with clear metrics</p> <p>Guide/FAQ section explaining how to interpret results</p> <p>Mobile-friendly sidebar with links to other hardware test tools (keyboard, mic, camera, screen)</p> <p>Who might find this useful:</p> <p>Gamers wondering if their mouse is double-clicking</p> <p>Anyone buying/selling used mice</p> <p>People troubleshooting scroll wheel issues</p> <p>Those curious about their mouse’s real polling rate</p> <p>Anyone practicing or testing their CPS for games like Minecraft or click-heavy titles</p> <p>The tool respects privacy — no data is sent to any server. Everything runs locally in your browser.</p> <p>I’d love for you to try it out and let me know what you think.
