My cat is terrified of this box and I cannot get her to even go near it which is more a problem with my cat than this box.

I have only been able to test out the box by playing around with it but not had the cat actually use it so I speak of it as well as I can: it has a large footprint so it is not for tight spaces. It is super simple to set up, you will have it out of the box and ready for your cat in a minute.
It is very quiet, you almost can't hear it running even when you are standing over it.
Clean up appears to be rather simple, more so if your cat wont use it.
The waste trap seals tight, so I am sure it will do a great job trapping smells.

The replacement trays are easy to find, they seem to be sold just about everywhere.

I am wrecked that my cat wont use it since I have been wanting a self cleaning litter box forever. I am going to keep trying, maybe she will come around.
