I can't believe some of you have never heard of it. If you have mosquitoes, you need one. They work, guaranteed, and I have killed deer while using one and was never winded. Not saying they can't smell it, but if the mosquitoes are bad, it's worth the risk. I don't care if I'm covered from head to toe, mosquitoes bug the crap out of me, even if their not biting. In a dry year, I may not have to use one because the mosquitoes aren't bad, but that's usually not the casein Louisiana.They have them on sale at a local store where I live for $14.95. I'm going to get another one. The striker on mine is messing up. Guys, if you don't have one, get one, especially if you live in the south.They are not expensive. They usually cost around $20.00.
