Chick Bator Egg Incubator 9108
I am used to larger incubators and all have the heat element on top. I could not get the temp to regulate until I taped the light bulb to the top (inside) of the dome. Once I did that I laid a piece of foil over the outside of the dome, over the bulb and got the temp regulated. This also provided for more space for the eggs and equal temp for all the eggs. With the bulb inside, one egg would be way to hot, while others were too cool. Other than that, it's fine for a one time deal, but not a replacement for larger incubators.
