I had allways used revolution and stronghold is the UK version of revolution it is the same thing it works so well and also protects against heartworms and intestional worms so that you dont have to give an added medication for those as well. My grandson is allergic to fleas and we have 2 yorkiepoos and a large australlian shepard that come in and out of our home. We never see fleas or any other pests on any of our dogs. I really like this product and will continue to use it as long as I have pets. I also appreciate auto order because that way I never run out. This site is also so much cheaper than buying at the vet I can buy a 3 month supply for all 3 dogs for what I would pay for a 1 month treatment at the vet

I have been using this product successfully for several years on three dogs. This product has never failed to keep my pets free of fleas and ticks and they have had no adverse reactions. Highly recommend this product

Have been using this for over four years and not one flea! Delivery like clockwork, and so much less $$$$ then the 'other' one... Great deal on a great product, thanks!!

I have been purchasing Stronghold/Revolution for my dog for about 5 years. My dog has never had a flea on him. The medicine is supposed to prevent heartworms too, so to be sure it is working I had him tested for heartworms at his annual check-up and he is negative. So, this medicine is real/it works. I'm in the US and I receive it in about 14 days. I am so happy because I save a lot of money and my dog gets good medicine. I also have recommended to my friends.

Purchased Stronghold for my multiple cats. Stronghold is inclusive in controlling fleas but other preventive control infestations such as heart worm, biting lice & ear mites. It comes on time; and reminds me in advance of pending shipments. Price is the best!!!
