5/5My old A10 was getting very slow so decided to get a newer samsung. Several family members and friends recommended Back Market so decided to give it a go. Wesite easy to use to enable you to pick the make and condition of a refurbished phone. It arrived the following day and was exactly what I had ordered. Transferred all my photos etc and so far am thrilled with my new refurbished phone. 😃

5/5I am very pleased with my purchase. It looks like a brand new phone, with no marks or scratches whatsoever. I was a bit wary about buying a refurbished one, but my son recommended Back Market as he has been buying from them for several years. Would definitely recommend.

5/5Received my device promptly with hardly a mark on it. What there was is a couple of minor scratches to the side which are invisible when the phone is in its supplied cover. Also the phone had a screen protector on it in addition supplied with a charger and cable. So all in all I'm very pleased with my purchase of a good quality phone at a fraction of the price of brand new.

5/5Excellent! Customer service was superb, keeping me updated on postage which was rapid. The phone itself was just as described, in pristine condition. Not only that, I traded my own phone for a reasonable price with no quibble. All in all a 5 star service from Back Market and I would recommend them to
