This is by far the best "fly swatter" I have ever used. It can be recharged so no need to by batteries and its safe to the touch which is good because I have kids. It is much easier and effective that regular swatters. Just catch them on a window, wall or even the floor and once they fly into it, they are shocked and killed instantly and you'll know as you'll hear it. It also has a light on there in case you are battling them in the dark. This product is a win, win and HIGHLY RECOMMEND if you have pesky flying insects in your house.
