Bests & Worsts Reviews from Amazon

I have been using frontline for years. I normally buy it at the pet store. I have had good luck with the product until I bought it here from the seller on Amazon. I do not think it's the real thing because it has not worked at all!!!!!!! It does not even smell like the usual frontline I buy at the pet store!! Do not waste your money on this product I tried it twice and it has not worked either time. I thought maybe the first time I just got a bad batch. Now I'm going to the pet store to buy more what a waste of money this product is!!!!! Beware!!!!!
