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 Tyler Fountas

I used this product on a fridge freezer. I like the dual display, set temperature and actual reading. I don't like screw connectors that don't hold wires. 16 gauge wire (for amperage) is stiff and stretches freely. Connectors don't have teeth to "grab" the wires. If a product is rated "20 amps" then the connectors must support it. I was so frustrated that with 3 wires connected and one wire disconnected I "hit the mole" trying to insert the last wire - I soldered them to the connectors. I prefer solder joints.
