I tried this about a month ago. With 7 cats in our house, the 'tub' of litter is the only way to go. Tidy Cats is our preferred litter and I appreciated the light-weight as I lugged it into my cart, to my car, and into my house. I was disappointed as the lid tear tab was defective. It didn't pull off and I wasn't able to simply pop it off. With the help of a pry bar, I was finally able to get into the litter. I fill the empty container with the waste scooped out of the litter box. The product was comparable to their other options for odor control. I didn't notice it being light weight when I carried out a full tub of waste, but at least the walk into the house was easier. Because of the problems with the lids and higher price point, I wouldn't purchase this again.
