What a disaster of a product. It looks aesthetically pleasing, but it has no functionality at all. Not only does the drain pipe take ages to connect because of the hassle design, but it isn't made to fit snuggly. Which means the urine and water used to clean the grass simply spills out from the bottom. My dog may as well pee on the floor, I'm mopping up urine anyway. About 20% feeds through the pipe, the other 80% of the urine merely falls right to the ground below. It's not very stable for larger dogs either, my Lab weighs in at 37kg and he is unsteady because of it's shaky design. Worst of all is the grass is unappealing for the dogs. Not premium at all. I was aware synthetic turf would be less appealing by default, but the grass isn't even remotely similar to normal turf. Cheap plastic you could pick up at the dollar store. For $445 I am shocked. Absolute rip off for a poorly executed design. Customer service takes forever to respond too.
