Love the size and wedge shape. Lasts forever, just pricey. Only corner box that fits in our laundry room and we can still open the dryer because the curved edge doesn't block it. We had the top entry for years and it holds up super well with occasional deep cleaning. Our cats are getting older, so we decided to try the front entry. A bit more litter gets on the floor with the front entry because our babies get serious about burying their treasure, but a litter trap mat will solve that issue. If you can afford and need the super sized unique shape- it's a worthwhile investment.
