I'd say it depends, do you have any long-haired cats?
I have had no luck with them in in the past, and have had to avoid them now as we have long-haired cats, which clumping kitty litter with long-hairs is usually a disaster with litter getting stuck on them.

I just think its part of the daily ritual, or in my case multiple times daily due to having a herd of cats. I don't enjoy it, but its better than the house smelling like cat waste.
