I have the NR360, as well. It's taken awhile to learn its' idiosyncrasies, but I'm beginning to like it! I had five eggs left in it at day 23. I tossed two - a quitter and a clear - and was going to toss the last three, simply because they looked "flat" inside and we were already well past hatch day. Something told me to let 'em ride one more day. I actually argued with myself out loud over it (DD looked at me like I was certifiably nuts!) but I ended up putting them back and going to bed. Lo and behold ... the next morning we had two pips and the start of a zip!
A word of warning for the NR360. Mine is my second of that articular model. The first was replaced for free because the turner died halfway through my second hatch. We didn't hand turn because, once we suspected a problem, it still worked properly every time we manually tested it. I'm paranoid, now, so I check several times a day to make sure that the eggs' positions are changing properly. Losing that hatch of critically endangered Nankins was heartbreaking!
