I'm not happy with my incubator, but I bought it without doing the research, so it's my fault. I bought a MagicFly and what I like least about it is that there is no decent insulation to keep the temperature from fluctuating much. I "calibrated" it, set the max and min, and wrapped it in a towel, but it seems to still heat up a few tenths of a degree more than I want or cool off more than I want. Usually no more than one degree each way. I don't have A/C and the temp fluctuates about 10 degrees in the house, daily. I keep it out of the sun and wind. And I'm returning it!
A friend is giving me her Little Giant that has a fan and an egg turner. It's not an old model, less than a year old. She was using it for chicks and I'll give it a good sanitize when I get it. She says it worked well for her, I should be able to get it on Friday, then test / set up for 24 hours before transferring them.
