Review on 🔥 Facon 8.0"x25" RV Tank Heater Pad - 2-Prong Plug, Up to 50 Gallons - Fresh/Grey/Black Water Holding Tank Heating Pad, Auto Thermostat Control - 120V AC by Steven Stager

I was a little worried they weren't working properly so I put on an ammeter and monitored them. 1 draws 0.1 amps when off, but it will turn on and off at the stated temperatures. The other is just on all the time, regardless of temperature, and the third probably won't even turn on at 27°F, and if it does, it'll only turn off and on for a few seconds at a time until it turns itself off random turns off amount of time. It sucks that 3 times 3 is wrong.
