very good

This product works just as Revolution would work. Same active ingredients, kills same parasites, etc.

I tell everyone about it. I have a cat that goes into seizures and would chew his toes raw. Vet gave a steroid shot but it didn't help. I realized that biting an itchy spot would trigger the fit, tried this product and he has very few and his toes have healed up.

Wonderful. It works quite well on my two large dogs and they do not have a problem with it being applied.

I buy this product to protect my animals from fleas and internal parasites, particularly heart worms. I find it less effective against fleas but I live in Louisiana where it is hot and humid for six months out of the year. I still buy the product because of the parasite protections Stronghold provides. I haven't found anything that really works on fleas in the deep south of the US. We spray the yard and that seems to be most effective for killing the fleas.
