Perfect size, great way to camouflage, and covers odor better than a box out in open.  I bought thins because at the time, I was in an apartment, so there was no great place for the litter box to be hidden. This was great! 
I have had this for over a year now, and the the little pegs to stop the door have come free. In hindsight, I would have used super glue on them or something like that.
