Has anyone used Zero Bug Zone?

Yes I have bought, four ZeroBugZone (www.zerobugzone.com) from Air Glaciers System units after seeing their informmercial on TV. I own a auto repair shop with 4 bays and we have mosquito problems. I figure any releif would be great. so i installed all four at once. One right in front of the entrance way into the store, two in the large garage, and one in the small garage. All the units are spaced out between 15-25 feet a part. Then I waited to see results. After three days, I did not see any difference. After a week, no difference, bugs are still everywhere. Flies and mosquitos, still annoy us. Not just one, but dozens. I figure it may need more time and more light. So I'll leave the lights on all the time, and even put lamps right next to it. Another week, no change... I'm a laughing stock now. They say there's a myth that if you hanging bags of regular water that's surpose to do the samething. I feel like i just bought some expensive water containers with a LED that lasted a day. So consumers beware. I will be returning the products.
