I bought one of these a few years ago when they were popular on the radio. It worked for awhile and did catch no-seeums and mosquitos, but didn't make a difference. Then I started having trouble with it going out, or not starting after repalcing the propane tank. They sent me another power pack since it was under warranty. The pack quit working within 2 months, right after the warranty ran out. I did some research, and lots of people had the same problem. It appears the company knows that the power packs have a finite life, and their business is based on selling replacements. DONT WASTE YOUR MONEY!
