This stuff is flat-out amazing. (1) Not super overwhelming and doesn't just "cover" the smell (especially when paired with the SpotClean Pet Pro!). (2) Doesn't smell like old lady's house (sorry grandma < 3). (3) A little goes a long way! The recommended amount for a full tank in the SpotClean Pet Pro is 2oz. (I think...) so you get 24 uses per bottle. I bought 3 of these and feel like I am set for life!
