I bought 5 of them because of the polarity of the mosquito to see the effect, but it took too long for the seller to make a mistake, and I have been using it for 3 days and it does not seem to work. There are 3 levels of 1, 2, and 3, which gives the person enough stimulation. Our mosquitoes are strong in our neighborhood. I think you should buy it carefully.Jun 03, 2018
