text: I live on my boat and spend a great deal of time outdoors enjoying the water and nature around me. An inevitability of that kind of living is MOSQUITOS. I'm enjoying the atmosphere of the little lights in the evening when the little buggers come out, but I'm enjoying even more not having to endure the bugs. I can't say they're 100% effective, but anecdotally can say that I feel they're very effective. I can also truthfully say that when I have them lit I am hardly bothered while my boating neighbors are getting eaten alive even with sprays.
