Title: great idea, but this product falls short
Review: The clamp seal that keeps the lid on is not secure enough to prevent bits of litter from escaping every time you flip it over. I use super clumping litter, but the action of rolling the container always breaks up the urine clumps - thus mixing it back in the the "clean" litter to go back into the container. Also, my cats don't seem to like it. I basically have resorted to scooping out the urine clumps which defeats the purpose of this container.
