Review on 🌡️ DZS Elec Temperature Controller: -50 to 110 Celsius / (-58 to 230 F) Programmable Thermostat Module for Heating/Cooling Control, DC 12V, NTC Waterproof Sensor Probe, LED Display by Jeff Sorensen

I rarely write reviews but this product was so bad I thought some reviews would be helpful. In short, the controller does not work. I put the first one and the relay did not turn on the load. I asked to be replaced. Installed the second and also did not help. Also, none of the settings can be changed. In both cases there were no problems with the return of goods. It seems like they know they have a defective product but build their business knowing that many people don't bother to return a defective product due to its low price. I strongly recommend not wasting your time with this temperature controller.
