I have the LG still air and I purchased it at Tractor Supply. Mine seems to be working fine. I have chicks due to hatch in the next couple of days. Follow advise on this website, and you shouldn't have a problem. I bought the turner for mine, but I am hand turning the eggs....I feel like they do better when you turn them by hand. Just a feeling I have...call it instinct. The incubator is holding temperature fine...you just have to tweek the dial ever so slightly you change or adjust your temperature. Very sensitive...any time you adjust it, make sure you watch it for an hour. Throw away the silly little thermometer that comes with it. Buy a hygrometer/thermometer at Walmart for 7 bucks. At some point I want to install a small computer fan to regulate the temp throughout the incubator better. Good Luck with whatever you decide!
