Awesome. I love the frying sounds it gives off, hearing those nasty buggers fry to bug heaven or wherever.  Bought a second one for a relative, and she loves it.  Works especially well on moths. Haven't seen it fry any mosquitoes, unfortunately, and for flies?...useless.  The small, gel-like packet of bug pheromones provided is not very effective for attracting more bugs that I can tell, and it does not last very long. This small packet sticks underneath the unit and supposedly the heat from the lamp will set off the pheromones...naahh...gimmick.  Nota Bene: the cord is very short; you'll need a heavy duty 3-prong extension cord (like one of those cords for garden work).  Would I purchase again? Duh...I did.
