What is worth telling us
The useful reports are the specific ones. Which controller or phone you used, which browser, and what the page did or did not show. "The vibration button stayed grey on a PS5 pad over Bluetooth in Firefox" is something we can act on. "It does not work" is not.
What happens with what you write
Your rating and your text are stored and shown on this page. Nothing else is kept: no account, no e-mail address, and nothing about the controller or screen you tested. Reviews go live immediately, so please keep out links, personal details, and anything you would not want a stranger to read.
