DROK Electronic Thermostat Controller, DC 6-30V 24V Digital Temperature Control Board -50 to +110 Degree Celsius High Accuracy LCD Digital Micro Temp Control Switch Module with Waterproof Sensor Probe

Screen is bright and easy to read. Controlled a small 24vdc fan well until the fan failed. Setup is also easy, for basic temp control instructions weren’t even required. For audible alarm they would be needed, but not what I bought this for and this instructions are quite clear if one wanted to use this feature. Can be powered via terminals or micro USB as seen in photos.

Quality seems to be good, and it's easy to configure. Wish it could switch to fahrenheit, but it's not a big deal because you set it and forget it. When you cut power to the controller it retains the settings. We're using it to control a small ventilation fan for the electrical compartment in our camper, and it's been working flawlessly! Small size, great value!

Il fait exactement ce qu'il doit faire. Par contre, un peu dur a programmé

Great thermostat. They just need to improve the instructions on it. Follow other buyers reviews for instructions, it helped me way more than the product instructions. Overall i'm happy, it's small, simple and works!

Works well. I see some comments about failures. I have used it for 2 weeks now and so far so good. I have it wired to a video receiver. The cabinet doesn't meet the recommended clearances, so I bought this to control a USB powered fan. (connectors bought seperately). The wiring isn't completely intuitive. I got out a VOM to understand what the connectors and switch did. To be honest, I then looked at the wiring diagram and it showed the same thing, but I didn't look until I was done. Of note, the USB is 5v, so it does work a little lower than 6. I'm sure others might want a USB powered option.
