This is an electric Mosquito swatter, mosquito killer, mosquito trap, mosquito bat or  mosquito racket, depending on how you want to refer it as. It is very vital at home for killing unwanted flying insects like mosquitos, flies and any other nuisance small insects. Simply hold the handle, turn on the red switch, press the larger button located on the side of the swatter till the indicator light is on and wield it towards the insects so that they can touche the net surface. Once an insect touches the net, it is electrocuted and dies immediately. It has an inbuilt battery power which you simply plug into a socket for charging. Remember to turn off Power (main) switch when the Swatter is not being used in order to reduce the free consumption of the battery. Also recharge the Swatter when discharge becomes faint and the light is weak. Before using after purchase, charge the Swatter untill it is fully charged. They come in colours like blue, green, red, orange, yellow, etc. depending on availability. The swatter can be used indoors in the house, outdoors like at the garden or in an office. It's also very light therefore can be portable anywhere.
