i do not know how these people say they hatch eggs from this piece of crap, it is "just a bowl with a light bulb" it seems like it wouldn't do anything, but, i bet someone can make a semi-homemade incubator, by attaching the light bulb to a water heater thermostat, and find a computer tower that has the big fan and the little tiny fan, then attach the little tiny fan to a cell phone charger, and put it in the incubator, i dont know how this would work, but if that was all it took to make the piece of junk work, than more people need to do that, rather than throwing the 20.00 dollars they spent on it in the trash, once they get it to their house and realize it is a bowl with a light bulb
