I had an ancient large Styrofoam incubator from years back. When this came on sale, I decided to try it. The instructions are definitely lacking, so I visited Vevor's website to see if I could get more info. There is an FAQ section that might help some. But by looking at the photos and illustrations, I further figured out what I was doing wrong. I had put ALL the 6 enclosed turning bars in and the turner was not working. Plus, the eggs didn't really sit correctly. From the photo, I saw that only 5 of the 6 bars were in place. Voila! That solved my issue. The rotation light came on and all is well. Apparently they give an extra bar. Also, they include jumper cable type wires in case one needs to hook up to a car battery. Hmmm... I have a dozen eggs in there and we'll see how we fare in 21 days. This is definitely easier than my old one. The temp is pre set. I feel it might run a little high, but only by 1/2 a degree or so. It can be adjusted, but I will leave it for this batch and see. It is easy to monitor and adjust humidity. And regardless of what vevor says, humidity DOES matter when the chicks are hatching. So do your homework, read up, and watch the humidity per the egg types being hatched. I do like the compact size. I can put this right on the kitchen counter and it's hardly noticeable. I give 4 stars because of the difficulty in figuring out the initial set up. The manual doesn't tell the whole story, and for me, set up wasn't totally intuitive. Edit: it's been 22 days. I candled at 7 days and found 3 of the eggs not fertilized. Darker olive eggs are opaque so candling is impossible. I could only hope. Well, we have 8 lively chicks, and one more egg pipped and waiting to finish hatching. All chicks pipped, zipped, and freed themselves easily. All strong, upright, and quick-witted. They ate and drank almost immediately. We are happy with the incubator. The humidity has to be micro-managed. But with this compact unit, it can be set up in the hub of the home,
