I have the Suro and my first hatch is scheduled for July 29th. It is very easy to use, I like the design. The incubator sits in a cradle that moves back and forth. The digital temperature and humidity guage seems to be right on. The automatic pumping system works great. The only time I have had to take the lid off was for candling the eggs. The eggs appear to be developing on schedule and the air cell is good. My eggs were shipped to Alaska, and a couple of the air cells are detached, so I am hoping all goes well.
There were only two small concerns that I had.. the cradle was hung up on one side and did not turn well when I first got it. I adjusted the screw and it works great now. Someone just got the screw a little too tight. The other thing is the incubator has dividers that hold the eggs in. (like little fences) I did not have a full incubator, so my eggs would fall to one side. I fastened a twist tie to the two dividers and the eggs stayed in place. Those are real minor things. If my eggs hatch okay on the 29th I will be singing praises for this incubator. It is like using a bread machine.
