Using Revolution on your dogs?

Is anyone using Revolution on their dogs? If so, how long, and what do you think of it?

I'm just using it for the first time this month; I've always used Frontline Plus before, for many years, on both cats & dogs. I tried Advantix on the dogs one time last year and didn't like it - they were itching within 2 weeks. But I decided to try the Revolution when I saw it had Heartworm meds in it, too - so far, so good.

I'm just wondering what everyone else thinks of it.
