Kenstar is worst air cooler I ever have . the cooler is not good because I did not felt anything good with this product even in summer the working of this cooler is little low and many alternatives are available I brought this cooler in last year and even when I am going to start it its not working completely not working and the worst part of the kenstar is service and support customer service is very bad . cooling is bit good the sound coming . quality is bad its completely not justify its price .
