    So to preface this, I don't usually leave reviews because I'm really bad at remembering to leave one at all. But my experience here was so stellar that I wanted to speak up, in case anyone is on the fence about buying from Back Market. I definitely recommend it. I purchased a Galaxy S21+ listed in "excellent" condition. From my understanding of the listing, the phone would have a screen in perfect condition, and a body with barely visible scratches. The phone came in on time, but when I opened up the box, it was immediately apparent that there was a very deep scratch on the screen. There were also a few other scratches that were not as deep but still clearly visible, and the body also had some sticky residue and was dirty. I was immediately appalled by it and was preparing myself to have to deal with a painful process to get a solution. But in actuality, I came back to the website and was able to find my order and easily process a return claim. I was given a UPS label to return back to the vendor to repair. Back Market kept me notified the entire time when the item was received. Within hours the vendor notified Back Market that they could not repair it and processed the refund. I...

    It took me five months of wavering back and forth whether to use BM, NOW THAT I AM FLOORED when I received the S21+. Conversion was simple since the Samsung phone came in flawless condition. I'm swearing to people that I don't know that it is actually new handset! BackMarket is now the best way to get a quality device without the headaches. Still cannot believe the excellent condition of the phone I ordered.

    I have bought at least 6 phones from BackMarket over the last 4 years. There are 5 in my family that I have bought from here. The phone is always as advertised and we never have had any issues.

    “I COULD NOT BE HAPPIER! And I WILL USE B.M. FOR EVERYTHING IN THE FUTURE!” After reading some of the reviews about people getting their items with deep scratches or customer receiving the wrong item entirely. I was really worried! Then After finding out that it doesn’t come direct from back market, they use 3rd party sellers which I didn’t know until after the purchase, I was freaking out, because I didn’t have much money to spend. But I COULDNT BE HAPPIER! the shipping was FAST and EFFICIENT!! I COULD NOT BE HAPPIER! For selecting the “Fair” option I truly expected THE WORST! But it was the TOTAL OPPOSITE! There were just normal wear marks on the front and the back was flawless! It was the closest you could get to brand new without paying crazy money! Thank you guys for selling great products!
