I do like my LG. I do not think it is a disservice to anyone to have options, information and success stories plus failure stories.
I purchased mine because I was not sure if I would like hatching. I read that most hated them, had a hard time with temp and then I read about what worked for those that like the LGs.
A stable room temperature
the LG does not adjust itself if the outside room temperature dips down 30 degrees due to a window being open at night or heats up 20 degrees due to sunlight coming in a window. I have mine in the closet we have under our stairs (center of the house, no windows).
A fan and egg turner I think all incubators should come with them not as on option.
Do not be quick to adjust the temperature and when you do, make super tiny adjustments. Then wait a couple hours for the incubator to level out.
Once you set the eggs, do not adjust the temperature. It takes up to 48 hours for the incubator to heat the eggs you just put in there. Give it time, then in a couple days if you need to adjust
.just a small bit and then wait.
Get a thermometer that you trust.
I am not lying, the above has worked for me for two years. I wish I was lucky
then I would buy a real incubator with my lottery winnings.
