    This is the 3rd time I've purchased a refurbished phone from backmarket. I am absolutely a loyal customer and fan now so much so that I have recommended this site to everyone I know who's in the market for a new phone tablet ect. I love my s25 and have had no problems and the trade in program rocks! I love it!

    Great purchase on my end, I was still using the S9 before this so it was due for retirement unfortunately, still love my S9 though. This S21 is better in several ways. even being refurbished. it charges in a bit over an hour, the back is plastic so you don't need to worry about the phone flexing in your pocket and cracking, an issue I ran into with my old S9 partly because I procrastinated getting a case. The cameras on this are great, the quality is nice, and I'm not sure which processor it uses but it runs really smooth. It's got the average 60 hertz display and the fast and snappy 120 hertz display that you can cycle through, 9/10 phone imo

    The battery doesn't last as long as my dead phones did. Also the charging port does not seem to have been replaced at refurbishing. The charge cords tend to fall out real easily making charging very tenuous. Ed Kersten 5020 12th ave s Mpls MN 55417

    The phone was in excellent condition. I had no issues swapping phones and have run across no glitches. I am very pleased. As someone who doesn't need the newest item, just a good functioning one, I am pleased to find a place I can find refurbished items without worry.

    Got the Galaxy S21 5G 128GB unlocked (ordered the "excellent condition") and have used it with my Straight talk service for a few weeks now.. So far perfect! This is the second time I have ordered a phone from this website and have been happy both times!

    I couldn't be happier with my phone. I use boost mobile and had no problems activating this phone with them and keeping my same number. The phone itself looks brand new and I haven't had any issues with using it. I don't think the phone looks purple I think it's more blue but others say it's purple so I guess that's just me lol the phone is just the S21 so it's a smaller phone than im used to but I've had no problems adapting my daughter recommended back market to me when I was looking for a phone and I have no complaints. It shipped quickly and even comes with a one year warranty so I felt secure buying from them and I was not disappointed.
