Review on Ximimark DC12V 🌡️ 50-110℃ Waterproof Thermostat Temperature by Jason Richardson

Failed to load media. Edit: I bought a few more to figure out how to use it reliably, here's what I found. Firstly, the rated power of the relay is unreliable, so you should connect it to a more powerful relay that can actually handle the intended load. Second, even though it uses mechanical means to switch, it can still burn out due to current surges when switching. The coil of my large relay was sufficient for this, so be sure to use a flyback diode with your relay. Third, it can get very hot during operation so ensure your circuit has adequate airflow and if possible preheat/cool the controlled air space with another device (possibly a heat gun or lamp if possible). . so it only works to keep the specified temperature, not to reach it at room temperature. After applying these changes it works like a charm and I haven't had any issues since. It is currently installed on my 3D printer body. The software works great! There is no doubt about it. And the instructions, although very roughly translated, are easy to follow if you read them carefully. But when I turned it on, it only worked for about 20 minutes. A ton heated up and the relay stopped working. The relay must be rated for 20A and has been connected to a 10A load. I suspect this is poor quality control as other reviews suggest it has worked for others for the same issues. Purchase at your own risk.
