After buying a phone for a family member through Back Market and seeing the quality and service I bought one for myself. The phone arrived on time and well packaged. The device was exactly as described. This is my first refurbished phone...so far so good.👍

I was looking for a replacement of my old samsung s6, I had seen back market advertised & as I didn't want to splash out for a brand new phone I gave them a try.I was a bit apprehensive about buying a refurbished phone but I needn't have worried.Phone I ordered was samsung s21+ in excellent condition & that's exactly what it came in,not a mark on it & even has original protective film on front & back,battery was at 78% but soon charged up to 100%, very well packaged & excellent delivery.Thanks back market one very happy customer 👍 10/1

The Samsung Galaxy s21plus I purchased was as described "Excellent". As good as new as far as I can tell. Delivery was on time and the product was well packaged. Very happy with my dealings with Back Market. First time I have had a refurbished phone and I would certainly purchase my next one from Back Market.
