This litter box is excellent and just what I needed.  I live in a one bedroom apartment in Chicago and there really is no great place to put the litter box.  So far, I haven't smelled ANYTHING.  The box sits behind my couch in the living room.  Both of my cats took to it quickly.  I left a litter box outside of the box just so that they can adapt.  In a matter of a few days, both were using the one inside the cabinet and stopped using the one outside of the box.  I think they prefer the privacy :).  I would highly recommend!  Four stars because I feel like the cabinet doors could be a little sturdier/better aligned, but otherwise a great quality product and worth it.  I got the espresso one, wish there was a lighter wood or reclaimed wood version that would match my living room décor.  This does just fine though.
