I have never written a review for a product because I believe that a product should do what they say it should do. However, this little bug zapper has changed my life. I bought one 2 years ago and have sang its praises to anyone that would listen. I am “that” guy that if there is a mosquito within 20 miles, it will find me and bite me in the most annoying place in the world like behind your knee or a toe knuckle. I recently got back from St John in the Virgin Islands and sadly forgot my little bug zapper device. I didn’t realize that St John has ANGRY little mosquitoes and Noseeum jerks that even make the woods in WI seem tame. After the first night, I had giant swollen, mental breakdown level bites that made me consider using a cheese grader to support the itching. More annoying, my wife is one of those people that never gets a bite. I almost itched my legs off on the flight home. I got home last night, grabbed my bite zapper and went to work zapping every accumulated bite from 10 days. Some I had to zap 2-3 times because they were the equivalent of wearing jelly fish as socks. This awesome little device gave me my first good sleep in 10 days. Didn’t wake up itching once. Even better, when I woke this morning, all the swelling in the bites was gone. Just make me a brand ambassador at this point because I will sing the praises of this device from the mountain tops. Next vacation, I will probably remember to pack this device before I even remember to pack a toothbrush. Incredible and thank you
