Kenstar makes a good quality cooler’s, in that it had made Turbocool DX which has a lot of power in its fan. And this cooler can make a room cool within half an hour because of its big body size and its powerful water motor in it, I was using this cooler from 2 years I did not face any problem while using it, it is a best cooler upon cooling and the air comes out from the cooler is so high.
