This little dude does a great job. I was worried with it's size, but it's been going now for about a month and killing everything that comes near it. It's better than the stinger brand because it's not got a garbage transformer, also it has larger openings, so bugs can actually get in. The mosquito thing that goes on the bottom was worthless because it's got cheap adhesive on it. It fell off the first night and wouldn't go back on.
