You said before that the Nurture Right was mishandling the eggs - turning them wrong in the outer ring. Do you have the turner for quail eggs or are you using the standard one for chickens?
I have a NR360 and I'm not that fond of it. This is what I have done to make it more usable.
First it needs a mat on top of that sharp edged floor. What I use is also used in shelves like to set glasses on. It's a foam checkboard pattern that is soft on the toes and still lets the humidity circulate.
Then I added the quail sized egg turner and a riser ring that gives you a 3 inch fence that keeps the chicks from spilling out when you take off the top. That can be exciting if you have a bunch.
Speaking of taking off the top, I added a couple of those stick-on plastic hooks to actually give some kind of a handle for the top. It's easy to slip and drop otherwise.
And since there is zero insulation, I added a blanket that goes around the whole thing and clips in the front. That helps stabilize the temperature. You have to not block air vents though.
I bought mine new 1.5 years and used it maybe 8 times and yesterday when I went to fire it up, the fan made that horrible noise that says the bearings are dry and/or shot. So I am waiting for a new fan right now. The fan is easy to replace though and not expensive.
I have too much invested in this one to toss it, but, if it were to disappear, I'd look at something else.
