Works great! I initially bought the more expensive temperature compensated gauge which did not work at all. Apparently it was defective out of the box. I replaced it with this and finally have a gauge that works. Very pleased with it.
The casting of the case is unacceptable in any case (tso or not) The back plate still has spurs from the molding process. The back plate bows in the middle between all four corners. I have not installed or run this gauge, but not expecting much. This gauge would be OK at $30-40.
