I have had my Cat Genie for 2 months now and I don't know how I ever lived without it. There were 2 reasons I really wanted the cat genie 1) Get rid of the horrible smells 2) I have a dog that was getting into the litter box and leaving half eaten "surprises" in the living room. The cat genie eliminated both of those problems.
I have the litter box setup in the laundry room and on cat mode which makes the spray last forever. Next time I will definitely get the scent free packs though because the smell is too strong for me (but only for like 20 mins after its sprayed) but its way better than the smell of poop.
