I so wanted to love this product. I have serious back issues so the light weight was a real seller. And it is easy to scoop out waste. (This is why I chose 2 stars instead of 1). But then I started to notice I was coughing every time I used it. When I looked up, the area I had the litter box in was putting out an amazing amount of dust. So I have now gone back to the heavy Precious Cat litter. It is almost dust free and really controls odor. It is a little harder to scoop but not choking on urine soaked dust makes it worth contending with the weight.
