My personal experience with the Little Giant was kind of a headache. The bottom half was so shallow that I'd lose heat and humidity in a matter of seconds if I had to open it for any reason. Also, the eggs were so close to the heating element, that there was a big temp difference between the center of the incubator and the outer edges (and that's with the fan). I actually had to build a new bottom out of wood making the bottom now 8 inches deep. With that much air to heat up, it heated up evenly throughout the bottom and holds the temp longer in case I need to open it. It works great now. It may work differently for someone else though.
