Hello guys ! I have taken this mosquito repellant by a salesman who visted my house a month back. He had assured to me that this repellant is good it will keep the msquitoes away and it acts like a precaution. But guys its all lies. No effect is there to the mosquitoes by the use of this repellant. When I keep it on, the mosquitoes are still there. This machine also creates noise pollution . I took this machine for 150 rs. He had told me that he is a medical student and so he knows the good effects of its use. But guys its all fraud . Once it even fell from my hand and broke so I had to stick it using a cellotape.
