Delivery was properly fixed and the product is great for the price! As already have written a couple of users in front of me, the valve closes off not completely what me and the cat does not bother. It is good that the tub is higher in the back than the front. Our cat did not want to clean only when the lid was on the wall behind the higher has held quite a bit of litter off the ground. Meanwhile, however, he goes top with lid and this I need not even take off when I want to clean the toilet because the flap above provides an aperture which is a nice size.
