I'm unfortunately more than disappointed with this product. the effect is not there at all, even after regular and prolonged period of use. There are still just as much mosquitoes go as before. Effect = 0 !! I live quite normal central in the city, it is not a lot of mosquitoes at night on the road than, say, lying on more rural location or riverside houses. I would definitely advise against buying !! Saves you money !!
