I have it almost two years and works like a dream when I am it already bought for 33 euros do not know why the price went up. It has very good strength, for example when you want to connect the old way hifi'm taking so at soundcheck integrovanvanej it vecsinou to date and the volume of 100 and IT guy to play sparingly and to hear from those speakers Niese sufficiently energized pritejto soundcheck but not play it as well as you would if you put in actinic cd, has great equalizer while I tuned each speaker so that suited me, even when those preferences are totally nothing like game, music, GX, hifi, it just totally kazi sound best tune themselves according equalizer settings I prefer my music and movies, 7.1 or 5.1 virtualizaia is also needed for anything that goes wrong in the films celi sound, and the fun is the date when a hifi prefix so it still has a worse sound than an integrated soundcard
sound quality is a simple little pekna not heat with a good equalizer except equalizer is plug in the cell to adjust the sound sucks incompatible with win 8

Quality / price. Drivers super, after ejecting from usb system immediately switches itself on the internal. I use it on a laptop computer - versus internal card is about something else.
