I use the lil giant and am quite happy with it,I have had great hatches with it hatching coturnix,the most important thing is to let your bator adjusted to the right temp before setting the eggs,then,,most important,,do not,,,do not,try to adjust the heat control,and leave the lid shut I use the same thermometer and they work for me,at lockdown I don't add water because the hatching will bring the humidity up to where it needs to be.and I say again,,do not open the bator during hatching or try to adjust the heat control
