The seriousness of the production, aesthetics and comfort are at the rendezvous. I previously had another Belkin brand support, albeit at a lower price and without the HP but there is no picture and after a month the fan started to purr. For this, one wonders if the fans turn. With the volume adjustable HP a few clicks, it's the essential accessory for music lovers or musicians who like to travel without having to lug their stereo and more they sound good. Side perfect size for a 13 ", 15 but see beyond HP will be covered. A really good investment!
