Bought the Russet color;very attractive brown.  Easy assembly if you can follow visual cues; it doesn't really have any written instructions.  Sturdy without being to heavy.  Love that the material it's made of can be easily wiped down.  The larger size is just what I was looking for b/c my cat stopped using her old enclosed traditional litter box.  There is plenty of room inside for her to stand up and she doesn't looked cramped.  Easy access to clean.  She used within 3 days of us putting it up.  We had  litter box  in another room that we gradually moved closer to this one....needed to get the other one out of "public view".  We left the door open on day 3 and she used it.  The next day, we closed the door so she had to enter through the opening and she has been fine ever since.  Very happy with purchase!
