This is so damaged product from world class brand Samsung. My grandpa use it more than a year and he really feel unhealthy because which air this air conditioner provide is such a mixture of some harm gas and air which really hurts your skin and your health. Coolness is limitless but its sound noise is so more which I really feel bad. In my way this is a symbol of harming bird. So dont choose this and see another option. This is sometimes not work as user friendly but is okk. Because with this air conditioner we accept only this. So young charmers join another healthy option which refreshing your mind and charm you.
