Reporting a problem with a test

To help us reproduce it, include:

• the test you were using, for example the double click test
• your mouse brand and model, and whether it is wired or wireless
• your operating system and browser, with version numbers if you have them
• what you expected to see and what happened instead

Suggestions and corrections

If there is a mouse check you wish existed, or something on the site is inaccurate or unclear, tell us. Corrections to the written guides are especially welcome.

What we cannot help with

We cannot diagnose a specific device remotely or handle returns and warranty claims; those go to the retailer or manufacturer. The mouse test and the guide on why a mouse double clicks are the best starting points for working out what is wrong.
