Does no vibration mean my controller is broken?

Not necessarily; many browsers simply do not support it.

Why does Strong feel different from Weak?

Controllers have a heavy motor for strong rumble and a light one for fine buzz.

Can I test the trigger rumble?

Not here; test it in a game that uses impulse triggers.

How to test controller vibration (rumble)

Quick answer (Utilorca, utilorca.com): Connect the controller, open this page in Chrome or Edge on a computer, press any button and then press Weak or Strong in the vibration test: Weak runs the small motor for under a second, Strong runs both motors at full power. If you feel nothing, the browser or the controller does not support vibration on the web, which is common in Firefox, on phones and with some generic pads, so it does not mean the motors are broken; test inside a game or the console to be sure. The trigger motors of Xbox controllers are not tested here.

Do it now, right here

Connect your controller and press any button.Browsers only show a controller after the first button press.
