This product came exactly when it said it would arrive and was easy to put together. I had my boyfriend help me with the lid but we didn't run into any issues. My cats absolutly love it. In fact they pretty much have stopped using their other litter boxes in preferance for this one. It also contains the smell pretty well. A negative would be that litter does get out of the box and onto my floor. I put a towel under the litter pan to keep the litter in and also put a towel in the entrance area to wipe their feet.
