Putting this together was very easy although I wish there was a physical copy of the instructions instead of just a QR code. 
It is easy to use and functions very well. I love the deodorizer- it smells like the Avatar ride from Disney world. It's very quiet and doesn't scare my animals. Everything about this litter box is cool and so high tech, however, it is meant for smaller cats. My cat is rather big and doesn't fit comfortably in it.
