I was off to a Canada Day fireworks at a park that always has a lot of mosquitoes and black flies. So i asked a friend of my husband what would he recommend. He gave me this to try. I put it on and went to the fireworks. It worked amazing. It felt so lighweight on my skin instead of being greasy as other brands I have tried. You don't need to put a lot on just a little dab will cover one arm or leg. I will definitely buy this again. The mosquitoes did not bother us this year. It also smells really good.
