Overall this is a very good product with a high specification at a very good price and the seller is very helpful. I found the sound quality and the picture to be excellent but I have had some some problems with the products touch screen.
The touch screen is not accurate enough for me, In music mode, using the stylus which came with the product I am not always able to select the function that I want, for instance when scrolling down the list of tracks etc. when you get to the bottom of the screen and press the icon to move down the list, the device plays the track instead of moving on to the next track. I have found this very annoying at times. I have tried the touch calibration in the settings menu but this has had no effect.
Sometimes nothing happens at all when you touch the screen softly or hard. In general I have found the touch screen to be a bit random and unreliable when it comes to function selection which is a shame because otherwise the product is excellent.
I am a professional musician and I bought this product to play my backing tracks through my amplification system when I am playing live to an audiance, but I can't trust it to select the track properly every time, so I will have to find sonething else, probably costing a lot more money.
If you dont mind the above problem then this is an excellent product for you.
