Negative Positive
Title: Doesn't work. Buyer beware.
Review: After two applications it has not made any difference. I believe they are using the Hartz brand to sell an inferior product to value-oriented shoppers. I'm guessing they cannot mimic Frontline or Advantage because of patents, so they created their own recipe to get into the market. It doesn't work -- my opinion the product is so bad it is bordering on fraudulent. In the meantime I now have a bigger problem with fleas inside the house. Go with the vet recommended brands and save yourself the trouble.
