When I saw the advertisement then I thought this was good product for killing of all the mosquitos this was killing the mosquitos but it was a very bad product in which I have been experienced so I am requesting you buyers don’t buy these worst products. The bad qualities as well as the worst qualities of all out flash guard 1. If any one has the smell related elerzies than please don’t use this product because it is releasing some useless gases. 2. My personal opinion is stop the usage of all out flash guard because when we fire it all the mosquitos was not dead at that corner only the mosquitos was dieing but not in other corners or middle of the room 3. When we fire the most dangerous gasses as well as the most dangerous elements were releasing so stop using this very worst product .
