I have 3 of these temperature controllers and 2 of the humidity models from Inkbird and all 5 work great. Setting your preferences is not difficult at all. I would suggest that you take a few minutes beforehand to memorize the 8 digits in the system program and the 2 digit abbreviation you see on the display for each of those digits. For example, in programming mode, the first digit is "Temperature Set Point" and the abbreviation you see on the display is "TS". There is a block diagram in the instructions that clearly shows all 8 locations. Once you've memorized (or at least become familiar with) the different positions, try scrolling through them all once or twice before you start changing the values. When you see how easy it is to switch from one location to another and enter and exit programming mode, go ahead and set the values you want. I have a room that I need to change settings on a regular basis and Inkbird controllers make this a lot easier than any other digital product I've used. I keep Inkbird sensors alongside very high quality thermometers and hygrometers and they never differ by more than a tenth or two of a degree or a percentage point. As long as I need these kind of controllers I will always use Inkbird!
