Yep I use the Mosquito Magnet. It rocks!
A must have down here in soaking wet Florida.
After being off for a few months during the winter, I recently fired it back up. No bites since!
A very worthwhile investment, go for it. I would also recommend getting a small inline gas gague, it helps you know when it's time to swap tanks.
I like to think of the co2 its giving off as fertilizer for my plants, too. hehe
