    I was very disappointed that my Samsung Galaxy S21+ would not accept a Sim card. I mailed it back to the refurbisher on August 19. They had it back to me by September 1. Battery life is great. One charge lasted all day including 4 hours of video. Speed was excellent. I bought a model that only rated good, but the case and screen seem perfect to me. Very good purchase.

    After having a phone for a year and a half the mother board went out. I was not going to pay that price again just to have it go out again. I was recommended to try back market refurbished. I bought a Galaxy S-21 Plus. It arrived in just a few days. Looked and operates like a new phone. I've had the phone for a little over 3 weeks now and the only problem I've run into is getting the right case for it. I keep ordering the wrong size. Right case is on the way. Should be here tomorrow. I'm so exited. Cross my fingers it's the right one this time.

    The phone is in a pretty good shape. No scratches and the only thing I saw was a smudge which I can ignore easily. There was a mishap with FedEx but it wasn't the sellers fault. I recommend purchasing from this seller because they sell great refurbished phones.

    Awesome phone at a competitive price. The S21+ I bought is in basically flawless condition and everything appears to be in full working order. I would absolutely make this purchase again a second time, and have no regrets. 10/10. Backmarket rocks and buying refurbished is the way to go.

    First time buying a refurbished item and it was well worth it. I ordered two, one for me, one for my wife. They both arrived sooner than expected and were exactly as advertised. These phones are in great condition and work like new. We put in our Sim cards and it worked flawlessly. We've had the phones for about two weeks now and we have no complaints. I will most definitely return for future purchases. Thank you Back Market!

    Before I bought a phone from Back Market I bought a refurbished phone from Amazon. It arrived with a broken plug that still had lint in the charger port. Which shows they didn't even clean the phone, nevermind refurb it. But the phone I received from Back market was perfect. It was shipped fast with enough communication to comfort me. Amazon doesn't even help to stand behind the phones you buy from there. It was a difficult process to return it. I highly recommend buying from Back Market over new.
