I bought the vizio vz mp3 angry bird mp3 player before 3 month ago. so it is worked properly till one month after that the bettary backup was reduced. It gives only approx one hour backup. It is not give proper sound quality in some earphones. And it’s small display gives very bad experience song name don’t show properly. The storage of song collection is bed . But the price is very high according to function. In this price range. Many types of mp3 player available in market. So I think my review will be useful for you. Thank you.
