I am not impressed with the design of this product. I was immediately aware of how noisy it is compared to my other one (different brand). I have struggled all the way through the incubation period to take the lid off one-handed to turn the eggs, and even then to return it to its correct position with the vent and water tank.
Then having hatched not even half of the number of quail eggs, all the chicks just ‘fell out’ when I went to transfer them to a brooder with there being no ‘lip’ or bowl effect at the base to keep them contained while I picked up one at a time to transfer them.
The only feature I do like is the option of filling the tank externally, although even so, since I have to take the dome right off to turn the eggs, since I can’t hold it off with one hand, I could easily fill an internal water tank at the same time.
