Rated 5 out of 5 by Works Wonders After many attempt with other products thinking I would save money with No results, I broke down and finally spent the money and purchase Advantage II. I was amazed how it worked. No more fleas. I guess in the long run, it would of been cheaper if I started with this product then wasting my money on all the other failure products I tried. Shipping was fast too! I highly recommend this. It's a miracle and me and my doggie Thank You! Woof! December 27, 2016

Rated 5 out of 5 by No Ticks! Haven't seen any ticks on my dog this fall although many other friends have said that they've pulled live ticks off theirs. November 8, 2016
Rated 1 out of 5 by Waste of Money This product does not work anymore on my animals. I've tried other flea topicals for my dog and two cats, but chose this one because it always worked great. But, this time when I bought it, it did not work. Two weeks after I put it on them, my animals are still scratching and I even found fleas on one of my cats! Won't purchase this brand anymore!
