Have used the past month~Live on a pond and have all kinds of flying bugs and mosquitos since we have 100 hanging back deck lights that stay on most of night~Seems like this Zapper unit has greatly reduced that mosquito & flying insect population. Am very happy with it. I have it hooked to a Wuuds 32555WD Weatherproof Outdoor Outlet Remote Control Kit. Deck lights are also hooked to another Woods Remote Control. It's nice being able to control both from inside the house.
