Review on 🌡️ Inkbird C206T Heat Mat Temperature Controller with Day and Night Thermostat, 1500W, 6.56 Feet NTC Sensor, Fahrenheit and Celsius Degree, -58 to 212F by Darnell Evans

In my opinion this beats all the other options including LUX WIN and WILLHI temperature sensors if you just want heat control. Don't waste your time and money with one of those yellow EZHeat plugs, they are not accurate and rarely work as advertised. Inkbird is the most versatile temperature switch I've ever come across. It has a power rating of 1500 watts and a very wide temperature range. I am currently using it to keep my RV with a heater above freezing. The only downside is that you'll probably need to read the instructions to get used to programming, and you'll need to set the on and off times, but you can still set the interval to have it on all the time.
