    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.

    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!

    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 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 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 recently purchased a s21 from back market in the "good" condition and I'm so happy with it that I probably couldve got the "fair" conditioned s21 and still been pleased with it!! Seriously there wasn't anything to complain about...No obvious scratches or dents of any kind and overall battery is almost 100% brand new with 96% overall battery health (not meaning 96% charged but 96% in comparison to how a brand new battery should function. This has been such a good experience that it doesn't make sense to buy the newest most expensive phone or even a midranger, I will always buy older refurbished flagships from now on, it's the only logical option. It's the equivalent of why you don't buy a car brand new as it is more economical and generally better to buy a slightly older used car if you want to be wise with your money and get the most bang for your buck deals!!

    Received the refurbished SG21 Unlocked,in a cool brown looking box with a note on box to take good care of phone, it was exactly what the seller claimed to be, more than perfect had no issue charging nor starting put sim in had service switched within minutes from wireless provider. Just perfect. Definitely will be purchasing more electronic devices, finally found a site that's honest with refurbished products spent half the US dollars than some of these other Joe burgers who want to overcharge on refurbished phones. Thanks Back Market!!! Not sure who Greg is but thank you for saving me the headache on searching for affordability of my needs!!!
