Hello friendsI buy a good knight mosquito repellisor 1 week earlier and instead of good night I have worst nights .This mosquito vapouriser does not let me sleep because of his unpleasant odour which affects me and does not let me sleep.And this is not user friendly this is harmful to us , it causes irritate skin and stomach pain like problems .The body is also made up of very cheap plastic which gets broken from the height of only 3m.The refill has to be changed after every 15-20 days .And one refill costs rs 80 and it takes 2 refills in a month which means rs 160.They cheat us please dont buy this productHigh money cheap productsThankyou
