So far works good.  the only reason I am not giving it a 5 star, is that it doesn't have a bug catcher on the bottom.  A small removable plate or something would have worked.  If its outside, not a problem, but I have it in my garage since we were having mosquitoes get in our garage and eating our kids.  After a good night, I have a pile of dead bugs on my floor I have clean.  I usually just blow them out with the blower, but a $.25 piece of square plastic on the bottom to catch them would have made it great.
