Review on Derale 16731 Fan Thermostat by Jacob Ferrarini

I like the switch for the most part I wish the fans would rotate to 165 degrees instead of 185 degrees but it works and I shouldn't be complaining for that alone. My only concern is that you must be very careful with the switch during installation. Make sure to take it apart and install the base with tools (wrenches or sockets) first. Do not use any tools on the sensor itself. Tighten it by hand as the copper pin is very brittle. If you tighten it as an assembly it will definitely break. learned this the hard way!
