This product is great! Assembly took longer than I had anticipated but every piece was clearly labeled and fit just right.  We have recently moved in  to our new house and our master bedroom had space for the cat litter box  but after putting so much effort into decorating the room we didn't want a regular plastic box to cloud the space. It took about a week for our cats to adjust to their new "room". 
 The unit is tall enough for them to walk in and the protective liner inside is fantastic. The drawer  on the inside is a great bonus and we keep our plastic bags and shovel in there. We also purchased the sand catcher step and it works like a charm. We had seen this product at a cat show for $250!
