These days the weather is very hot so , I have purchased this fan so that I can sleep happily.but all those hope of my sleeping go to vain because of the quality of the fan, after a few days of purchasing the fan some irritating noise came from the fan which disturb me a lot, and the air passing quality is also very bad, So I have stopped using this fan and purchase an other fan. So friends I will never recommendyou to purchase this fan.
