I purchased a Therma Cell last summer and used it here in Indiana while fishing early mornings and evenings and it worked great. The real test came when I took it to Canada on a fishing trip in June and it really worked to keep the skeeters and other bugs away. Since then I have purchased additional units and use them when camping or sitting out on the deck at home in the evenings to keep the skeeters away. They can be worn on your belt or sit them on a table at your campsite or in your boat while fishing. They are good for up to a 15 square foot area. Anyone else out there used these? If not, I highly recommend them. I found them to be much cheaper in price at Menard's at end of summer clearance for around $10 each and they also sell the fuel cartridges and repellant tabs. I purchased the carrying cases off an internet website at a reasonable price.
