Title: Lentek
Review: this product did not work for me in south Vietnam. I have it turn on and mosquitoes still land on me and bit me. My friends noticed that I attracted more mosquitoes when I was wearing it, so they make me take it off after killing a mosquitoes on my forehead. Waste of $$ for me.
