I have one works fine, I did set a heating pad under mine ot heat the water/ver so it keep humidity high with the bp eggs. At the time the eggs I got were not planned for and I was trying 2-3 differnt things while waiting on it.. and i had 100 % hatch rate I did place it on my desk in my room so i could watch it more closly.. ( might bee nwhy the eggs got a litle dehyrdated. SInce i had to keep wiping he considation off the look in part. but it worked great I did set it up so the thermostat ran it more than the wafer piece but i had it set to be on before the thermostat would kick and click off at a safer range it gave me more control onhe themps specially with hte heating pad on the bottom ( outside) to apply an more stable temp.. If I get eggs this year I plan on using it.. I just soak the vem and turn it on.. it be ready
I used a light disfuser to prevent the eggs from getting into the mix since i had it too wet .
