This my friends is an electric fly swatter and I love it. I don't have screens on my windows so somethimes these little bastards get in so I got this, it takes 2 d batteries and zaps the shit out of flying insects. The fun is trying to get em and when you do it sparks. Fun as hell! The only bad thing is sometimes they fly off the grid and you have to look for them on the floor, whatevz it's entertaing, he he!
