I have 2 Advances, but without the pump. Absolutely love themAfter my most recent incubation heartbreak, I broke down and bought it: Brinsea Products Fully Automatic Egg Incubator for Hatching 24 Chicken Eggs or Equivalent. And, I bought the humidity pump too. I will be giving my BBS group another couple of weeks and then I will try again. Maybe I will have some baby pictures for show and tell.
