I have the brinsea eco 20, not the advance, the basic one.
My 1st hatch was 22 chicks of 100 % I also staggered my hatch and added eggs as I tossed eggs out, so I had a total of six more eggs to hatch 3 on one day 3 on another 100 % on those also. I hatched at 55% humidity, the little buggers were popping right out with no problems at all.
To hold the humidity for hatching I found it worked very well to take a thin rag, I used a dish cloth. Fold it the long way, dampen it and slide it under the egg tray.
