My first incubator was an R-com mini. It would hatch out 3 chicken eggs or 8 quail eggs. I purchased the quail egg tray because I was starting to hatch quail and the R-com mini was not too expensive.
Well I have to say I was completely impressed with the operation of that thing! It worked for me over and over again. It never malfunctioned and did exactly as it was supposed to do. The only thing I didn't like about it was that it did not have a humidity gauge in it. So I put in a small meter on the side.
But if your R-com 20 is built like my R-com mini, I think you will enjoy using it and it is a fine product!
Good luck!
