Does exactly what it should and dies VERY fast. If you own (as I do) two huge and frankly "fragrant" dogs this stuff is a blessing. I even carry one in my coat pocket when i walk the dogs because - guaranteed - some-one will want to fuss over them, usually children. Parents are always thrilled when you offer this to their kids after stroking two huge slobbery mastiffs!
I works - you need more than this?
