Complete disappointment.... I had to buy a separate memory card, no computer recognizes it (I tried it on 5 different ones), so I had to transfer any files to the card using a card reader. It doesn't support the mentioned video formats.... it only plays mp3 and radio.....
I would not recommend it under any circumstances!!!

Difficult and unclear menu, problematic communication cable with the PC, problematic headphones, problematic buttons. I regretted buying it, and it caused me two scares (for my daughters). Nothing else

Very good features for the price category. Satisfactory sound but not with the provided headphones. If good headphones are used, the sound is fine for mp3. The buttons confuse you in their functions and are not easy to get used to. The battery does not have a charging indicator and you suddenly find yourself out of power. Overall, it is still an excellent purchase.

I don't like its functionality at all. The store sent me the same mp3 player three times due to a problem, and it has the same issue. It works at first, but then the screen turns white and you can't do anything. The third one they sent me still doesn't have anything wrong with it, except that the buttons don't press properly. Imagine that I only use it three times a month.

It does not support the mentioned video, it does not support writable files, lately it does not support mp3 either and keeps giving format error.
