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

I can't find a price for the functionality of this controller, but I'm again stuck without a working system, having just received my replacement order. I haven't even shipped the first controller which broke within two weeks and the new one stopped working due to repeated sensor failure. I only use the controller to turn the fans on and off above the aquarium. I conclude that the probes are not waterproof. I've done my best to secure a controller that at least works as advertised, but the sensors that came with this replacement and the original order quickly failed. The first died within two weeks, and at night its reading was over 100 degrees above the actual temperature. The replacement, which arrived on Friday, was accurate on arrival but read over 50 degrees Celsius more than it should have for two days. The probe tips in both squads were protected and submerged, resting on the rim just below the surface of the saltwater aquarium. The probe just plugs into the board so it can at least be replaced, but I don't see a way to just order the probe from the seller. In any case, they shouldn't fail within a few days or even weeks of use. If the sensors are not truly waterproof, please do not advertise them as such. I will update this review when I get help from the seller.
