Well mine burn better then that but I have found the approach to the burner is about 1/8 higher. and the puck doesn't clear the approach completely. So part is on and part is off the burner. Maybe just 1/16-1/8 but enough the puck don't set flush on burner. Just noticed it. But have been happy with the burn. So I will look and see if I can adjust it or clean it.
