Dont know anything about that model other than its automatic .i think its preset and cant be changed i have a 1602N forced air i have used it to incubate but usually just use it as a hatcher but i have heard the 1588 is a nice model for beginners.
Most of the stuff Iv'e heard on the 1588 has been WOW.Only bad Iv'e heard was something about haveing to add water daily ;but thats up for grabs cause I do not know where they live (maybe the desert area) its an unknown.cva34
honestly, i don't think its worth it, i'd rather just get a still air 1602n, pop a pc fan in it for like 7 bucks, and buy the auto turners, might save 20 bucks that way instead of buying the whole thing.
I have had a Hovabator 1588 for the past 2 years and I love it. I have had excellent hatches using it. The temperature is preset but can be changed if necessary ~ I have never adjusted mine. There is also a fan which in my opinion is very important. Mine also came with a turner & holders for both chicken & quail eggs.
