    The quality of the phone is very good, it does have a bit more cosmetic damage to the rubber case than I expected, but otherwise great. It connected to the PureTalk system and transferred my data seemlessly.

    Worked flawlessly right out of the box with brand new mint condition screens. Case had a few scratches here and there, but if you get through life without a few scars then you aren't truly living. Cost savings were incredible - my first buy from BackMarket, will shop them exclusively from now on.

    Can't talk to anyone. Emails only. I use my phone for work and need it daily. Can't afford to wait till the next day to fix my phone. Phone was supposed to be unlocked but it was set up for AT&T. Also they make it very difficult for returns.

    looks like everything is in order except for the battery. Did anyone else not get a battery too? Am I going to get fleeced and someone tell me that "battery sold separately"?
