Had to take a look at it since reading in fahrenheit seemed like a good idea, although I quickly realized it would confuse the heck out of me having some units in C and others in F. Looks like it would be a fine gadget for a keezer where you only want to use the cooling function, but it seems one of the downsides is it will only do one or the other and not both at the same time. Cons:
1. It can act as a heater controller or cooler controller but not at the same time. There is only one relay connection, so you can either hook up a cooler or a heater and program it to switch on the heater or cooler by temp. Other products have two relays so you can switch on a cooler if the temp gets too high or a heater if it gets too low.
2. Programming is too tedious. It requires a separate button press for each 0.1 degree of change in the temperature setting. The other one would quickly scroll up or down the temp settings as long as the programming button was held down.
3. Instructions are incomprehensible Chineseglish. Thank goodness there were some drawings. Even the marlins for the connections on the unit were in Chinese characters.
