Query: Save Your Money and get a regular box!!

This box absorbs odors after a week!! So for indoor use, it makes the house stink like dirty catbox. It's too much bother to scrub the box, and liners won't work with the box size or the rolling. The rollover action works well enough, but too many finer clumps are left behind to keep the litter fresh. I got rid of the box after two weeks of use.Get a regular catbox, liners, and use the new clumping litter with crystals--it works very well. Otherwise, plain crystals is the best for odor control.
