The odor control is really great! I'm finding it hard to scoop; the clumping is good but it won't sift the unused litter through so it takes longer to clean. The biggest con is the tracking (even with a large litter mat). There is dust all over my house and couch and I've had to clean clumps of litter off my cats feet multiple times. One bag lasts me about 1 week to 10 days.
