I like that it was easy to put together, however, it was a bit difficult to get it to connect to my wifi, it is 2.4 GHz so keep that in mind. Additionally, it came with a "deodorizer" with a screw on cap that you attach to something and slides in the back of the device, however, if its supposed to deodorize, its empty and there is no information with in the instruction booklet to explain that to you or where or how to get it. So I do still have a strong smell of cat poop which comes from the tray under the machine. Otherwize, I pleased, just hope I can get some answers on this deoderizer.
