I used to use these when I lived in Wisconsin. They did help a little, but I still found fleas and ticks on my dogs. They seemed to offer the best flea and tick control around the collar, which I guess makes sense. I have switched to topicals since I moved to Florida and had much better results. These were inexpensive and easy to use, but with the fleas and ticks in Floria, I need something more effective.

Pros: easy to use

Cons: didn't work well

I wanted to save some money by buying this, but ended up spending more. This collar does not work as it's supposed to. There were no fleas around the cat's neck, but they were everywhere else in the fur. So what's the point?

Pros: Pretty colors

Cons: No effect

My cats did not like this thing around their necks at all. Maybe it would have worked, but we will never know. It was a waste of money.

Pros: Not a bad price

Cons: Uncomfortable

One cat is alergic to frontline so I use these to at least help with fleas

Pros: helps with fleas

Cons: better than nothing but now as good as frontline

Didnt like it and neither did my cats

Pros: Inexpensive

Cons: Only works around the head
