I was a little worried about buying an incubator I wasn't familiar with, but it was a good price, so I gave it a try. I tested it out with a second temperature/humidity sensor, and it was exactly correct.
I was happy to find that once I got my settings correct, it stayed exactly where I wanted it without me having to make any adjustments. That was really nice.
Hatch day came, and I had babies! I usually get excellent hatch rates, so I have high expectations from my incubators. The good news is that my record continues, and all my fertile eggs hatched. I hatched big babies and tiny bantams. They all came out of the egg just fine.
I am happy with my purchase and will definitely recommend it to my chicken friends.
