I love the Nurture Right 360!
I'm on my third hatch and have a relatively great experience. 95% hatch rate is pretty darn good. I've also automated my humidity with a little water pump; I literally set up and walk away until lock down (without having to manually add water every day). I love the low maintenance, ease of use and digital display.
Regarding temperature, the unit has about a 1.5 degree difference between the core and the outer most sides. There is less heat at the core/center and more heat on the outer edges.
Regarding humidity, automating water input made it extremely easy to maintain constant and consistent humidity without blinking an eye. When you first start, add 5 ounces of water to chamber A and then add 4 ounces to chamber A daily. This will maintain humidity at 50%. Once you lock down, pour 6 ounces to chamber B daily. This will maintain humidity at 70%.
Regarding ventilation and airflow, it does the job; nothing fancy. I just wish it didn't sound like it was going to die all the time.
Enjoy! Cheers!
