Prosport Gauges :(
 

Guess i should have researched them more. They look great in my car.....just ratttle like crazy. I sent one back and they sent a replacement. Rattles just as bad. I've read alot of complaints about it. Its a shame they can't stick a 1 cent rubber grommet in the face hole to stop it. Oh well. Guess i'll look for something else.

We've found that using a drab of silicone between the button and and screen helps, or turning the screen in the gauge it self so it rests against the button. Hopefully you can get it figured out!

I put a tiny rubber grommet on mine and it is perfect.
