I have used this generic form of this product for the last few years. In previous years after applying, we could smell the product and it worked within minutes. Bought this last night, new packaging and noticed no smell. This product does not work at all. The second box is going back. So disappointed. It was like applying water.

I used this for about two years, but it stopped working a few weeks ago, early October 2021 I noticed my dogs itching and they’d come down with fleas. Now I’m in a nightmare, trying to get them out of my house, vacuuming constantly, using pesticides indoors, etc. But

We have always used Frontline on our dogs and cats. When I typed Frontline in the search bar on Sam's website, this product came up. I used this 30 days ago and used again last week on our pets.

Great product!

Doesn’t work as well as frontline plus. Animals still have a lot of fleas several days after treatment.

I bought this for my 80 lb lab and so far so good! Price was very affordable and ingredients are the same as frontline! Will definitely repurchase!

I bought these for three dogs and two cats and they do not work my animal still have fleas and the money was just thrown down the drain outrageous that they're allowed to sell this claiming that it works it does not

My vet said that while the active ingredients are the same, it is lacking the ingredient that makes it flow through the blood system. It is only effective exactly where you apply it.

I’ve used this with no problems for a long time. This month, I pulled numerous fleas and a tick off my indoor dog. Something has changed and this product is no longer effective. Save your money and buy Frontline Plus.

Works well.
