Since I can't sleep I decided to test another incubator:

It holds 16 eggs, the smallest of the three so far, and has a carousel design. It's the loudest of the three I've ran, so far. The lid as a few small notches that are barely noticeable. If they aren't lined up properly it doesn't close completely. So far I'm not liking this one as much as the last 2.
Edit: I'm also not seeing any vent openings. That means if you accidentally add too much water you'd have to remove the lid to suction some out. I have feeling this one will be at the bottom of the list.
