Query: Disappointing

I was hopeful that I would love this box, but I don't. You cannot use it with regular litter unless you want a dust storm in your face. I tried it with fresh step. You can't use it if your litter box is tucked in a corner because you need lots of room to roll it. If you need to pull it in order to roll it on it's top, it is very hard to keep the sliding locks from coming loose. There is more than a "little" bit of litter that escapes from the seams, requiring a clean-up each time it is rolled. I was using 2 conventional litter boxes and didn't get as much litter tracked as I did with just one roll. I gave it 2 stars because it is a neat idea, just not for me.A tip for first time users: Don't put too much litter in the bottom or you will have a tray of litter in addition to the waste.
