I would like to give my feedback ahout kindle paperwhite . that was not good experiance for me so I want to share with you first I want to talk about battery life . battery life is not too long . I though battery life is long enogh for reading but it was not . and this is 3g tab and so you can not use 4g card in this tablet so I suggest you if you want to use four g you should not buy this tab and go for another tablet. I suggest you iball and micromax . I did not like kindle paperwhite so much I will give one star
