The same model I brought to my home 3 year before in very hot summer. This make our room cool similar as 1 ton air conditioner dose. Actually I like it’s silent& smooth operation. Which works silently in night times which doesn’t disturbs sleep. We run this air cooler for 4 months daily in night times but EB bills doesn’t affect it’s operation. So if any one like to buy cooler I will suggest kenstar.
