I notice that the new Liners are thinner material than then Original Liners. The Liners, Cardboard Tray, and Tension Band fit seems good. After a week, the Cardboard Trays have already begun to show some liquid stains and penetration.
The Charcoal Filter Kit Clip and Housing fall apart and prevent use.
Cleaning the Flip Litter Box is much improved with the Cardboard Tray and I continue to monitor the durability of the new Liner.
