Review on 👨 WILLHI Digital Temperature Controller with Over Current Protection - 1650W, 110V, 15A for Heating and Cooling -22~572℉. Ideal for Reptile Freezer, Greenhouse Temperature Control. Model: WH-1803B by John Benjamin

First impression - unpacking. I was surprised that the packaging looked more like a high tech device. I could do an unboxing video. Important: * The display is easy to read. * The accuracy of the temperature sensor differs by 0.1 from other measuring devices. * The procedure for programming the heater on/off thresholds was relatively simple.* The user guide provides simple example procedures.* Your programmed thresholds will be retained if the unit is unplugged (at least for a short period of time). My only suggestion for improvement: The font for the instructions can be enlarged 2x or 3x to improve the first user experience. Let's see how it stands the test of time.
