Fabulous product
Oh wow this smells great! We take trips to relatives at times with our dogs, and the guest room can begin to smell like the dogs; this makes it smell better (less embarrassing). It smells great, it's small and thin and can pack easily, no leaking noted, medium strength which I like as it's not overpowering. Great value. Recommend.
