Have you used it a lot? So far everyone I read has positive reviews.
I'm super new to incubating, so take this with a grain of salt. But yes, I used it three times last spring.
You'll want to put it some place where the temperatures are stable, and generally warm. My house is quite cold in the winter (no central heat and no working fireplace) so we consider 60 degrees to be downright balmy. The IncuView recommends a temp of at least 65 I think? That's not a problem for most people.
Even so, I was able to get a decent steady temp by putting it on a double thick bath towel.
If you've got some prize eggs, you might want to start out with a test batch to get used to it, but it's not hard.
The real joy is actually getting to see the chicks hatch, in great detail. I had ours on the coffee table and it was a terrific show. Really.
My hatch rate was something like 24 eggs go in, 18 or so made it to lock down, and 14 or so came out. So, all in all, not too bad, considering that mostly the eggs I hatched were barnyard b***ards. Of the Jersey Giants I put in, I had 14 shipped eggs, two of which appeared to be blanks, or early quitters, and five of which were so porous that they dried up quickly in the IncuView and caused a humidity issue for the first week, until I realized what was going on and chucked them. They had shells that were very bumpy on one end, so that was definitely a fault with the egg, not the incubator.
That was my first time using the IncuView. Taking out the porous ones, that's seven out of nine shipped eggs that hatched. So that's not a bad result, actually.
