I like mine now, but for the first couple of days was going to return it. I had it running for a few days to try to get the temp to even out, but every time I opened it, the temp would go crazy for a quite a while. DH said not to open it, so I told him to figure out a way to turn the eggs without opening it, or get me something that I didnt have to mess with. So for the egg turning, my husband (who likes to tinker) made a very small hole in the right side wall and put a piece of wire through it that is attached to a pipe that lays across the middle of the incubator. I put the eggs in an egg carton with holes cut in the bottom, and the cups for the eggs straddle the pipe that dh put in there. The egg carton is lifted off the bottom of the bator because of the pipe, and there's a handle on the wire that sticks out, so all i have to do is turn the handle and the egg carton rocks from one side of the pipe to the other. Not a good description, I'm afraid, but like I said, dh is the one who designed the thing. So, I can turn the eggs three times a day without ever opening it and got 7 out of 8 to hatch that way. I think number 8 didnt hatch because I opened it a few times to take the hatchlings out as they dried off. So, that's my fault. I have 12 more in there right now, it's been at 99.5 since I put them in there, and the only time I've opened it was to add a little water for the humidity. Next Sunday is day 21, so fingers crossed and we'll see how it goes.
