This is an excellent product to mp4 sound is enjoyable and mp3 sound quality is a little less good and it is normal, as all the mp3 sounds, say you should put a little less strong. The touch screen is very good when we add an anti-scratch protection film that allows the slides to be more fluid, without it you really press hard and the finger grip on the screen is really unpleasant to scroll, (cuttable protective film tailored to the crossroads 8). Finally I would say it is small but big or so small but tough, it's a real product that few people, and frankly for the price it's a great deal and very good. Would definitely recommend.
