I have one....I think its fantastic.
Humidity is not hard to control.
I dont have the humidity pump, but would like to get it.
Everything about the thing is super easy except adding water, and even then I think its easier to add water than with the hovabator. All the eggs inbetween the dividers sit in a little tray and you just lift the tray and add the water. The tray is also hady for taking the eggs out to candle them, etc.
It runs fantasically, comes up to temp super quickly and it has a digital readout with both Temp and humidity, which is ultra accurate so you can get rid of other thermo/hygrometers. The only con is that it doesnt hold more eggs, but the larger capacity Brinseas dont work with the humidity pump.
I have a hovabator genesis, and this is definitely the next stp up in incubators.
