Review on Temperature Controller Thermostat Waterproof Programmable by William Pacino

The only thing written on the back in English is the model number (XH-3001) and 3 ratings. The 12v120W rating box is enabled here. I'm not an EE but I can at least understand that the rating is 10A. I'm still no EE, but I don't think I'll ever run 10A through 22Ga wire, but that's what it does. I'm tempted to change it to 18 or better, but we'll see. Came 2, maybe I'll see if a stream can handle it. Hope it doesn't start a fire. I will definitely test it before installing it to run the heater in my RV. I don't want to tinker with the relay.
