I had a really hard time getting my NR360, I kept calling the different TSCs who kept telling me call back Wednesday, when the shipment comes in. Well, after a week, " it is out of stock at the warehouse and will be a week before they get one, and another week before WE get one." This was at a store about 45 min away. They couldn't get one transferred from the one store that DID have it because it was a little too far away (I am in AZ). So my husband went there and got it, about an hour and a half away. I'd called ahead and had them hold the LAST one, and when he got there there was someone else trying to get one!
I don't really trust the thermometer on it, but then I don't really trust any thermometers I put inside either, because the first time around the ones I'd put inside read it as low, so I bumped it up (100.5), figuring it would average out. They all hatched a day early. I had four that pipped externally before pipping internally.
The second hatch I put it at 100 degrees, and I had a really awful hatch rate, only seven out of the 22, but none of them pipped the wrong way, and they hatched closer to the right time. This time around I am leaving it on 99.5, and seeing what that will do.
What helped me out a lot were the assisted hatching articles here on BYC:
