Review on Jet Performance 10115 JET Thermostat by Alex Solano

It's just a Stant Superstat that's been slightly modified but still uses the same V-notch technology. It opens well, although another review says otherwise. I've used Stants Superstat in the same way as Jet, and I have to say Jet works a little better. The only difference in design is the tapered top of the brass piece (the Superstat has a flat top) which I believe improves water flow.
