I'll start. I have had 3 incubators. the first, a RX7, never hatched a thing. was still learning but my problem was every time I would open in incubator the tray would fill with water and in maine, I have since learned, you don't always need to put any water for humity. 2nd was the little dome incubator (it's actally the 3rd but I'm getting there) works great, hatched 3 chicks last yr, just needed to fuss a bit with the foil to make the temp right. and my last- an avey incubator (let's just say it's pricey) . a set it and forget type. but get this, it is all custom made and the owner doesn't service what he makes after 1 yr. so mine is now breaking down, the ABS plastic in the turner is degrading. they have upgraded to a new model (all plastic instead of wood) and he won't cut me out a few pieces of ABS plastic for the turner even if I pay him. he's got his money and I'm sure laughed all the way to the bank. So I have found a turner that will fit inside this one and want to let everyone know, avoid the avey incubator unless you are a handyperson (in that case, you'd probably build one yourself! and save all that money). I will say the Avey did teach me a few things: mainly the humity in maine. I need to add water for fall hatches but not in the spring, they'll drown. and 2nd, don't buy custom made, expensive doesn't always save you money in the long run.
