Having the constructed-in photo voltaic panel to high off the battery charge is a good feature when away from different energy sources. Even when bugs aren't unhealthy it really works effectively as a battery-powered supply of illumination. It could be really great to have this bug zapper and reading mild after a hurricane! We plan to make use of it on our porch with not-so-good screening and while sitting outdoors in the evening. Like a 60's "black gentle" it makes some issues glow at the hours of darkness which is type of fun! The instructions are good and the switches to turn on the studying mild and set the lighting stage and for the zapper are simple to make use of. It has an LED that indicates when it is charging and fully-charged. We haven't left it out within the rain to check the water-resistance. It makes a loud pop when a bug meets its finish. The excessive-voltage wires are very properly protected however Judy did get a jolt while she was carrying it searching for mosquitos with the zapper on. She thinks it arced to the keys in her pants pocket so it might be able to work on bugs by static discharge just like the shock you get when touching a door knob in winter. It is vitally powerful! Best not to carry it around with the zapper turned on!
