Murdy is correct. I often hunt swampy areas here in Alabama. When it is early season, warm ans still the skeeters are heck. This product works great .... but only if it is still. Seems like if there is the slighest air movement the repellant envelope becomes ineffective. I will add that this was a gift to me ... and I sort of felt obligated to at least use it. I am old .... and old school. I do not usually get into the fads. A GPS unit and cell phone are about as high tech as I have gotten.

Frankly a repellent with 25% or more of DEET is what I use. I am a firm believer that scent cannot be well covered anyway, so I simply stay downwind as best I can. Plus I try to travel light.
