If you're reporting an odd result, a few details save several back-and-forth emails.
- Browser and version — Chrome, Edge, Firefox or Safari, and roughly how recent.
- Operating system — Windows, macOS or Linux, since driver behavior differs.
- Mouse make and model — especially for polling rate or DPI database questions.
- What you expected vs. what you saw — the specific numbers, not just "it seemed off".
This is a small, independent project, so response times can vary — but every message gets read. For details on what we do and don't collect, see our Privacy Policy.
