This bug zapper really does a great job. You can hang this zapper with the chain that come with it or sit it up right on a counter or a shelf. The light shines from all 4 sides to get the bugs come to it. The design attracts more mosquito’s, flies, moths & biting insects, eliminating them instantly by the charged. It has a extra long cord as well. In the bottom of the zapper there is a removable bug tray. The outer body is made of a corrosion & scratch proof aluminium. There is a on/off switch on the front upper left side. It does work I put this out side by my back door and this morning there was a ton of bugs in the bottom removable bug tray.
