I have one that my cousin has lent me it has been a pain in the but to get the humidity up above 20%, the noise they make is fairly easy to get use to. it kind of sou rrrruunnng rrrunnng rrrrunng there really is no description for the sound it is audible but not really loud, I can hear my TV over it. As they have posted the worst part of the incubator is the light constantly flashing, so you are gonna want to be able to close the door to the room it is in or close your bedroom doors b/c it is pretty bright since it has a fully clear top. I wouldnt mind it since I can close my doors but at this point a week later I finally have the temp regulated so I think, because everytime I think I do it goes out of wack, I can not get the humidity high enough using just the ring around the outside edge. Positives is you can see everything going on in the incubator, and it has a fan to move the air around plus a turner. If there is any other questions that you have regarding the bator I will try to answer them. But as I said I havent hatched with it yet still trying to get the humidity up and stable, hopefully will start a hatch it it by the first week in March. Brower company is pretty helpful as well.
