All out is considered to be one of the leading brands to control mosquitoes in india.In india , we see that many people die because of malaria, dengue which are caused by mosquitoes.So people here use different mosquito killers like all-out goodnight etc.I also used all out in my house .Recently when I went to a shop to buy mosquito killer then the shopkeeper advice me to try ALL OUT FLASH GUARD which I had never used earlier.So I thought of trying this new product of all out. It is a small sheet of pink coloured paper .On burning this paper it will generate some kind of smog which kills mosquitoes.The company claims to kill mosquitoes in about 3 minutes.But what I found was just reverse of their calim.On burning that sheet it generated smog of very unpleasant smell.It was a kind of suffocation in the entire room in which the sheet was burnt.And the most disappointing pary was that it had no effect on the mosquitoes present in my room. So based on my experience , I would not advice anyone to buy all out flash guard .It is totally waste of money .
