I used this with my hovabator incubator to keep the temp and humidity accurate, as I was hatching quail eggs (first time).  I had more than a 50% hatch, which was great as I ordered the eggs in freezing temps and they required 4 days to arrive.  I am very pleased with this product and would order it again.
