Now coming to product, exccellent finishing and built quality. Its sleeky and you feel geart to hold and use it. In my opinion the sound output is enough a laptop and comparatively better than other. So totaly a perfect and stylish laptop in this price range. Driver are available in the official site. Battery backup is epproxmately 4 hours. Sound quality is enough for home users. As is does not havr a graphics card, Otherwise I think it is the best laptop in this range.
