I owned this a/c from more than 4 years now and still its in amazing condition. The service from Samsung is fantastic and this model is been most sold. It cools smoothly and fast, The quality of this product is fantastic and is reliable and trusted. Comparing window a/c with an split a/c:- The look is not that stylish, This one is more compatible and compact. Maintenance of window a/c is lesser than split a/c. A must buy product and most sold and liked product by Samsung.
