I bought an R-com 20 and it was amazing. The entire top is clear for viewing. It auto turns amazingly well. I filled the water very three days. It was my first time so I was candling nearly every day and sometimes more, but it brings the heat and humidy back to your settings within a minute. It was amazing and I had an extremely high hatch rate. It is digital and does everything you need. There are studies i have read that show the hen determines the sex, not the rooster, and that incubation temp plays a role, although it is only by one degree. I don't know if its true, but out of 20 eggs, I hatched 75% hens.
The r-com is pricey, yes, but it'll last for years, is very sanitary, and all comes apart easily for cleaning. The parts are all plastic and was a breeze to clean and disinfect. I searched for months on incubators, and feel I found the best price out there for the R-com.
If you or any reader is interested, get the best priced R-com 20 from Steven Rericha. His email address is

The R-com is from Korea and ships directly to you from the manufacturer and takes about two weeks. Mine arrived in a timely manner and in mint condition. They also make the King Soru but the R-com 20 is hands down the better model. They also make a larger one that hold 50 eggs.
You can change the temp and humidity easily, and turn off the egg turner the last three days. Also, the egg turning can be set for every one, two or three hours, and it plays a cute song when it turns, which we made up words to and sang to our chicks. It was nice hearing it play every hour, reminding us our little, living chicks were turning over. The music can be turned off if you prefer.
There is a YouTube video some British guy posted that is short and helpful.
