r-com a lot of money, good temp & humidity control = automatic digital, rolls eggs every 1,2, or 3 hours. Got a smaller one on clearance a couple of years ago. Bought a 56 egg incubator, made in China - got 0 to hatch so far. Couldn't get it up to temp. Display push buttons not working. Got with the seller and they want me to check the wiring connections. So now I'm down to last minute and working on finding time today to check the wiring in the digital display. I don't think the plastic cover is thick enough to insulate and keep the heat in - just guessing. We'll see.What kind of incubator does everyone have and are you satisfied with it?
