It doesn't work, I called the store and they immediately sent me another one. Neither does this one work! Either I'm doing something wrong (which is highly unlikely because its usage is completely straightforward) or many of them are defective :(

It can be used as both a flashlight and a mosquito killer. Its quality (plastic) is not the best, but it does the job and saves batteries

It's great, it works perfectly. Be careful, don't touch it too much with your hands on the mesh because although it's usually harmless, at one point I touched it at the edge of the mesh with the crown and it gave me a strong electric shock!
