I thought that It was a best product in less amount . But after some time this Product is not working properly. I am currently using Zen Cinemax . But I was not satisfied with the product performance . This Product should be improved. its performance should be the same as the time pass. even though I am cleaning my data then to its performance is not increasing .i hope that they will improve there Product as the time pass. My Zen sound quality is very low. it is having a better user interface. I don’t think there is any other features in this phone . its style and Design is good, Look and feel is just like average smart phone . it is not having the value for money as per my experience
