All Out Machines are a kind of useful thing which everyone buy thinking that it will help to kill the mosquitos in the house. It never repelled a single mosquito from my room. It gives out very small amount of smoke from it which doesn't affects the mosquitos at all. You'll have to close the fan in order to see the little bit of smoke coming out of the machine. It's just useless which consumes your electricity for no need.
The coils are much better than these mosquito repellent machines. The foldable paper also helps a lot to keep the mosquitos away.
I suggest you to not to buy this thing. Instead go for a coil which does the work at a comparably less time.
