Review on 🌡️ CHENBO(TM) Digital Cooling/Heating Thermostat: 3 Pack with Waterproof Sensor Probe -50-110 °c Temperature Controller - Reliable 12V DC Control, 10A Relay Module by Scott Rodriguez

Very easy setup that takes less than sixty seconds. Programming has a power outage. The features are great. The only thing missing is the ability to display timing parameters in C or F. Bright, clear display. The imprint is small, the length of the sensor wire is sufficient. The sensor is waterproof. It's good. Poorly. The first device failed after two days due to a rapid voltage change approximately 0.5 seconds apart. The supply voltage is stable at 12.0 volts. The switched output through the built in relay is the same 12 volts at 6 amps. I'm replacing another of the three units I bought, but based on a failure rate of at least 33 percent, I wouldn't currently recommend this product. Update: Within 3 hours of installing the second of my 3 devices the 3 digit digital display fails. It would be a great product if the manufacturer paid a little attention to quality control. And now the third is out of order and does not supply power to the onboard relay. I bought this set of three for two specific projects and after six weeks all three failed. (one works intermittently) When they work, they're great, almost perfect. Almost exactly what I need on paper, I couldn't design them more perfectly for the projects I need them for. But, my god, Chenbo. A bit of quality control, right?
