Economical and good at reducing smell, but...
... be prepared to vacuum daily, as this litter tracks everywhere!
On the positive side, it's economical; it clumps and it's easy to remove solids, which can be flushed straight down the loo, making disposal very straightforward and hygienic. It is also the best litter I've found for suppressing smell from urine.
Despite the daily vacuum workout (which I hate; I despise housework) I wouldn't consider changing brand.
