I wasn't crazy about the molded hinge on the box, but it works wonderfully and "the boys" started using it within ten minutes of me replacing the old style litter box. I woke up this morning with almost no litter on the floor (I use to sweep the floor 4 to 6 times a day before) This litter box will do what it claims to do - keep the litter in the box (or on the lid) and not on your floor.
