I recently purchase this blue star 5hw18zag, as I heard that blue star is a good company, so I make my mind to buy it and I was right this superb cooling air conditioner is really awesome.it takes few more movements to cool down the room as compare to other air conditioner, but when the room is cooled up it seems to be a plesent surrounding around. all the guest enter at my room also ask about my air conditioner it seems quite good.
