    This is the 2nd Samsung smartphone we bought from Back Market. This Samsung Galaxy S21 5g Unlocked 256gb was listed as Fair condition and besides the few scratches on the back of phone, you would have never known it was a refurbished phone.

    I was in the market for a new phone and was very seriously considering taking out one of those "loans" from Smart Pay so I could purchase a decent phone. That was until my coworker told me about Backmarket.com! I was very hesitant at first about ordering a refurbished phone but once I did some research, I decided to take a chance and I ordered the Samsung Galaxy S21 5G 128GB in Phantom Violet, "Good Condition". My new phone arrived this morning and OMG - I am absolutely BLOWN away!!! It looks fantastic! There are hardly ANY visible scratches except for one small one on the front (the back looks flawless), it was extremely easy to transfer over from my old phone, delivery was super quick, and I just simply cannot express how HAPPY I am with my purchase! I am beyond grateful to have found Backmarket.com! I will update/write another review in about 1-2 weeks once I have had a chance to REALLY see what this phone is all about. But like I said, at first glance, I AM ECSTATIC! Thank you, Backmarket!!!

    I have purchased from BackMarket before (back in 2021) and loved my S9+! I recently decided to upgrade to the S21 and, of course, knew that BackMarket would be my best option! This time around I decided to go with the, "Good" condition option (went with "Excellent" for my S9+) and I'm honestly very, very pleased. There are a few scuff marks on the back of the phone, and there's a slight scratch on the screen, though neither are very noticeable! All in all, I would (and do!) - highly- recommend buying refurbished, and buying refurbished from BackMarket at that!

    I'm very pleased with the phone.l really enjoy not having to spend a lot of money on the latest and greatest products out there. To be able to buy a refurbished phone and have it perform as good as it does makes me happy.

    I was encouraged by another customer review to just take the leap and buy one of the refurbished phones. There was some fear, but the phones arrived sooner than expected and in excellent shape. So the Back Market experience was positive, we're just not sure we love the phones yet - there are some things to get used to and it seems to want to update more than we would prefer. Hopefully things will improve, but so far I'm not convinced we made the right choice.

    I would say that finding out about back market has been amazing to me. I got an S21G 5G Unlocked from Cellfeee (I chose excellent condition) and it has just been a free gift from cellfeee and back market. The phone was delivered sooner than it was proposed and the phone was really in excellent condition, I have searched to see a scratch on the phone but I haven't seen any. I have been enjoying for about 2 weeks now and there haven't been any issue, infact my phone looks brand new, people don't know that I got it as a refurbished product. I will certainly always by from back market as it just saved me hundreds of dollars and also I would always check out products from cellfeee as they have just proven their reputation to me. I got an amazing product with a token (with respect to quality of product). Thank you back market and also cellfeee for keeping your word. I will keep buying from you.

    I always purchase refurbished tech and I'm always very pleased. This purchase has been another great but. The phone looks and works like a new phone at like 75% less than if buying new. Why wouldn't you go this route? It's so much better!
