While this little contraption hasn't solved all of my problems, it certainly is a fun way to kill mosquitoes, and it has helped me to control the population to some degree. When you get one there's a little flash of light and a satisfying CRACK sound.... it's great! At night before we go to bed, I go on the hunt to try to purge the apartment of blood-suckers. Here is a picture of me "on the hunt"
I even take the thing to bed, so that it's within reach if I hear any buzzing around my head during the night (although it is almost impossible to get one of those suckers in the dark).
I have found that the easiest way to kill a mosquito with this thing is to wait until the mosquito lands on the ceiling and just hold the racket up next to him. But, sometimes, the thing gets away and I end up running around the room looking like a crazy person. Here's a video of a successful "hunt" last night:
Overall I give this thing a 10 for fun and an 8 for effectiveness. I also bought a little Raid mosquito plug-in thing last night, so hopefully that will kill them while I'm sleeping w/out needing active interaction from me.
