I have been very please with the performance.I have been running it for a week to see how it performs before adding eggs and it has kept a very steady temp and humidity. It is consistently running between 37.5 and 37.9 degrees C. which is optimal.I have it place in a room with no draft to help keep it consistent.It was very easy to set up.I added too much water to begin with and because humidity in my area was already high,it got up to 67% to start with and I had to remove water.I do recommend running it for a day or so before adding much water because the humidity may become too high if the humidity in the air in your area is high. I am pleasantly surprised with the performance of this incubator and I do recommend it for casual hatching activity.The incubator was easy to set up. The machine it's running nicely, It's very quiet and no faults so far. Last night all five of my eggs hatched, ducklings are adorable and doing well ! I'm VERY pleased with this incubator. And highly recommend it.Keeps perfect heat temp within.1 degree humidity is tricky but not bad once you get the hang of how much water to add.Really great product for the price and very easy to use. Highly recommend!Easy to use.Fully automatic,digital readout tells temp.Humidity,elapsed days and even sends alarm when temp or humidity is too low.First time i use it i had a 95% hatch rate.It is so quiet and seems to be turning the eggs and keeping the temp and humidity where it is supposed to be and etc.Maintains temp,humidity could hold better,but is a good machine for the price.Excellent temperature and humidity automation, extremely quiet and pretty of room.I really not like it’s hatching rate
