Delivery was on time. The phone itself came with a screen protector already on. (that was so nice) It has one or two little scratches on it but that is to be expected because its refurbished. Honestly once you put a phone case on you cant see it anymore. All in all I would recommend backmarket to friends and family. I'm so happy I got my Andrew (android) back lol!Galaxy S21 5G 128GB - Purple - UnlockedPurchased on March 25, 2024

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.Galaxy S21 5G 128GB - Gray - UnlockedPurchased on February 24, 2024

I was skeptical About buying a refurbished model but everything turned out great.The phone is an awesome condition.And it came with a screensaver already on the phone. There was no problems in updating the phone or getting it programmed correctly.Galaxy S21 5G 128GB - Gray - UnlockedPurchased on April 16, 2024

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!Galaxy S21 5G 128GB - Purple - UnlockedPurchased on February 27, 2024

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.Galaxy S21 5G 128GB - Gray - UnlockedPurchased on February 7, 2024

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.Galaxy S21 5G 128GB - Gray - UnlockedPurchased on December 27, 2023

Was delivered in timely manner and physically looks excellent. The characters on the right side of the screen repeat when typing as did my last refurbished phone. Assuming its a defect from an aftermarket display. Its too much of a pain to remove everything and return it. So, I'll just deal with it. Still a great deal.Galaxy S21 5G 128GB - Gray - UnlockedPurchased on November 5, 2023
