Bests & Worsts Reviews from Amazon

Does not work! I spent so much money on this hoping for the best and it does not work at all. The poop gets pushed to the back and the whole thing fills up with pee. This has happened with the last 2 refills. I have passed the return deadline so I am stuck now. I have already purchased 2 sets of 3 refills so I am all on over $300. I will try to contact the seller to get my money back but it is not looking good for me.
