    4363 is rated 5.0 out of 5 by 3.
    Rated 5 out of 5 by from Great stat I got this a few days ago and tested it against another so called "hi flow" thermostat. It was as close to a controlled experiment as I could get. I used a good thermometer, had the stats at equal levels and monitored water temp. The other stat was a 180 and the Jegs/Mr. Gasket stat was a 160 Both opened at the temp they were supposed to open BUT the difference is the Jegs 160 opened more and it was quite visible. I let the temp go to 200F. So, if you have high flow pump your low flow stat can negate it. So there more than temp to consider when buying a thermostat.
