I have used 3 incubators, including this one. So far, it is by far the best. highly recommend reading the insert included. At this point, we're down to 10 days, as indicated by the reader. and all is well. The only dislike, at this point, is the manual humidity feature. My other auto adds water and self controls the humidity levels. This one you add water whenever the alarm sounds or you notice it is low, which can ne tricky to get right. Shipping was quicker than expected and had all the parts and worked properly, and it was packed well. I may update upon hatch with how many, out of the 24 we incubated, actually hatched. So far we have very promising results. Also, it came with a great chart for the kids to use to track progress.
