Better than Frontline

I had been using Frontline for years, but last year it stopped working and I had a flea infestation. Several vets mentioned that they had other clients that were saying the same thing. Not sure if they changed their formula or fleas just became immune, but the Revolution got rid of them immediately and I've been using it ever since. And no prescription needed. Great deal!
