Query: Back to scooping litter

This looked like a good deal since I have 3 cats and get tired of shoveling through the litter box. However, after a few days I realized the negative things that concerned me. You can only use a small amount of litter, it does not control the dust problem, you have to roll it 3 - 4 times a day for the best results. So it's back to the litter box for me.
