Right now I have a new lg on my left side, no fan, no egg turner and it's full of peeping noises, on my right side I have an older lg with both fan and egg turner, no idea how old it is, it was bought second hand at a yard sale by a friend of mine for $5.00, I start my eggs in the old one and then the extra eggs that I have left I hand turn in the new one, I have not noticed any problems with temps.
I also have a hand built incubator out of a fridge, I purchased an electronic thermostate and have not been able to keep the temp the same 12 degrees difference is way to much. I am going to replace the thermostate with a waffer one and if I can get it to work right I will still use the LG.
So I guess I'm on the pleased side of the LG. They have both worked fine for me. And I'm thinking about getting another one.
I really like to hatch eggs. I need AA for hatchers.
