Having planned on hatching some peeps shortly......I had picked up a second hand Brower top hatch some time back. After receiving it and doing my homework, I read stabilizing the temps could be a problem. It isn't made of styrofoam, it is made entirely of plastic. Nice and sturdy I might add. But it doesn't have any insulation to it..... I saw a "blanket" that fits around it's diameter to retain the heat better being sold. So I measured it out....whipped one up myself....placed it on.....and it now holds a steady temp SO much better. As well or even a bit better than my 2 styrofoam hova-bators do. I really like it's design a lot. Entire top is clear plastic, fan moves the air right along and will be super easy to clean. Mine I has no automatic turner installed. But the base swivels left & right.....so you can manually roll the eggs. I am hoping the end result is good..... as I am liking it more & more. Anyone else use this model with success?
