I received this product in exchange for my honest opinion. It is very easy to assemble if you follow the detailed instructions. It also has some letters and numbers to guide you. It comes with everything necessary to assemble. Gloves, trash bags for the litter, a screwdriver to screw the bolts. It even comes with some air fresheners that go on the litter box drawer. The noise level is great. It is not loud  It rotates slowly. The only downside as of now is that the litter pan flips over when the litter is being cleaned. That makes some litter fall out. Not sure if I did something wrong or if it's just the way it is. It has to be connected to WiFi which was not hard to do. The pairing was easy. I can see everything on my phone and even change the settings.  I highly recommend this product. It will make my life way less stressful when it comes to litter odor control and maintenance.
