Query: Horrible odor control, too pricey, tracks all over !!!

I have four cats and we clean out the litter boxes at least once a day. I have used this litter for a few months and I am not happy with it. The odor control does not exist. I almost want to puke when I clean out the boxes. The price is not even worthy of it's performance, lumps break down and cause a permanent stench. And it tracks worse than Feline Pine. I am going back to Feline Pine because of it's superior odor control. I also had people comment on the bad odor since I changed. DO NOT WASTE YOUR MONEY!!!
