We have only been useing it for about 5 days. But I like the hova bator better for 2 big reasons.
1. The healing element is close enough to the eggs that the chicks could hit their heads on it. Fryed babies is bad
2. The hova bator is MUCH deeper. This ones changes temps anytime we open it fairly fast, because the space is in the top not the bottom. Also if you open it to get chicks out, the humidity will fall fast, the hovabators humidity was fairly stable when I grabbed babies when it got overfull.
3. So far, mine has been changing temps more then expected, not huge, but going from 97-99 and back, I didn't have the problem before.
Its a great price for the full thing, but I'm not sure if I would get it again. Ask me again in a month.
