One of my cats has asthma so regular cat sand kicks up too much dust. I found this brand and decided to try the large pellets (this one!) and have never looked back.
It absorbs extremely well and I sometimes have no idea they have even used it as the smell is minimal (when the litter box is filled to about 2-3 inches, it gives them enough litter to cover everything up and you really can't smell a thing). It can be a little dusty as the bottom (unavoidable), but if you give the bag a good shake, you are left with the pellets only. I have never had a problem with my cats refusing to use the litter box.
The large pellets also make it extremely easy to clean up.
I also love that it is biodegradable, as it can be flushed down the toilet (and has saved me many times when the poop bags ran out). I cannot recommend it enough.
