Yes, it works wonders. I saw a post for it here a couple of months ago and all the posters swore by it so I bought one(it was only $30 or so). I took it coyote hunting with me last weekend. When I first sat down the mosquitos swarmed me, but within 10 minutes of turning my thermacell on they were gone. They undercharge for this thing in my opinion, I would have paid $100 or more for it.
