Bests & Worsts Reviews from Amazon

I have been ordering this product since last year. Last year it was amazinggggggggg. This year I am not sure what is going on but the last 3 pack I purchased I used them all within in a month!!! I never had to do that before! I ordered them again and tried to remove the lining to see if that would work and nope. 3 trays in a little over a MONTH!!! The point of buying such a high priced cat litter system is to reduce the need to change the crystals so often. I don't know what they are using but these crystals can't be the same. And the lining on the box sucks. GO BACK TO THE ORIGINAL PRODUCT
