I also have a RCom King Suro, I got them both within a month of each other. I really like both of them, for convenience and accuracy. One lays the eggs sideways and one holds the egg upright. I haven't had them long so the jury's still out on what eggs are better where. I do know my RCom King Suro is much easier to clean! I over filled my RCom20 which you are not supposed to do and I did have a couple eggs that didn't hatch. I even bought the special egg slot shaped turner for it to help them to turn all the way and it made no difference at all.
