Okay, so far the MeeF is 'acceptable'. It keeps it's temperature well, although I really need to get a proper hygrometer to check the humidity. As soon as my daughter has stopped destroying my car (she 'borrowed' mine for work since hers broke down. And hit a deer last night!) I'll go get one.
It's only getting 'acceptable' right now because they eggs have to be *perfect* for the turner to work. If they're too big, or too round, they don't turn. I placed some paper towels under the tray and it helped with most of them, but still a few that refuse to roll. I'll be getting some shelf liner as soon as my car is returned to me.
So for the time being, I'm hand turning.
Oh, and it doesn't have much for ventilation, just the hole where you can top up the water tray. I may drill a few more holes into the lid later.
At this point, would I get another? Yes.
Also, Moony, it does fit 30 chicken eggs in the one tray.
