We have one, had it given, I wasn't that impressed with it, we left the eggs to hatch in it rather than aseperate hatcher, but had a poor %, the design means you just rock the whole thing over rather than turn each egg. either 3 or five times a day, we bought a cradle. but then we ended up splashing out on the Brinsea Polyhatch, much better, the bottom moves and rods across hold the eggs so they roll with the floor, you can then leave the chicks in there for a couple of days as well.
