The product is decent or I can say good enough in budget segment get my hand on it and used it for more then a month No software lags.decent audio clarity and headphones are cool.
but If you need a better sound quality product in this price go with Sony Walkman 4 GB version. Do not get deluded with high end features of this mp3 player. This product body gives you a feeling of Chinese cheap plastic build product.
even fitness meter is not measuring distance accurately but when kept in pant pocket and jogging, it is measuring little perfect.Overall it will be a waste of money on this device. Either buy iPod shuffle or Sony walkman in this price range.
