After an electrical fly swatter I can try with my parents, I wanted to also have such a great part. So looked at Amazon and a slightly cheaper model chosen: well, who buys cheap, buys twice. The swatter was after a short time the "spirit" on. Although the LED lit up obediently, but it was to hear no humming, but the insects that (almost) laughed themselves to death. The swatter went back - thank you for prompt refund at Amazon! And a new swatter was needed: the extra expense was worth it. With a sharp bang, it is now the insects animal to the collar. Highly recommended and admittedly also associated with a certain fun factor.
