Straight out of the box, item would not work. I'm not quite sure what the problem is with orders through Amazon.com here lately. I think they are abusing the items during processing and causing stuff to be defective upon delivery. Recommend to just go to a big box and pick one up for about the same price and if it doesn't work, your not out of the hassle of re-packing, ect.. When one needs a bug zapper, one needs a bug zapper................... not next month!
