Just got mine, works great, keeps a pretty steady temperature. I set chicken eggs into the incubator, with the little giant egg turner, hoping for a good hatch. I gave it four stars because it is a great incubator for the money. It has a digital thermostat, and a fan that speeds up and slows down when it needs to. The only few things that I can complain about are, the incubator is a little bit small for the Little giant egg turner, (But it still fits) and the fan makes a little wine sound. Overall a great product for the price.
