I would like to tell you regarding zebtonics sigma dj mp3 player. I bought it online from amazon. Com two months back in the beginning it was nice but after ten days of usage its quality begin to deteriorate. I used to charge it for one hour and then after half an hour of use it shows low battery. After one month of use it sound system became worst and lots of disturbing noises can be heard in between I bought it very costly and now I am repenting I should have not bought this worst product ever.
