    I was a bit hesitant to order my phone at first since I’d never bought a refurbished device before, and I had seen a few negative reviews on social media. But I decided to give it a try, and I’m so glad I did! The shipping was quick, the phone looks brand new, and it runs perfectly — you’d never guess it’s refurbished. I’ll definitely be ordering again!

    So far no problems. No issues with the screen, the battery charges and holds the charger for a reasonable time, and was able to insert and connect to Spectrum once they turned it on, on their side. It's for my Father, who is technically disinclined, so as long as the phone works, and the hearing aid app that he got it for, he should be happy. Or at least as happy as he can be with having a smart phone. ;o)

    Absolutely as described! Package came packed securely and phone works flawlessly. Wasn't sure what to expect but needed a second phone for my work phone. I wish i had found BackMarket sooner. I highly recommend!

    The phone came faster than expected. I bought the premium one, and there were no scratches front or back. Very pleased with the service and quality; will definitely recommend BackMarket to friends and family.

    I can honestly say this phone was better then described. The description labels this phone as 12gb of memory. The 512gb s21 ultra has a ram of 16. My only concern is that the battery is not 100% but still lasts near all day and charges quickly. I will continue to monitor the battery situation.

    The phone is in great condition. ONE tiny nick in a discreet spot, can't even notice! No scratches on screen or back . Definitely worth the money I spent. Phone works exactly how it suppose to. Another plus was fast shipping. I couldn't be happier.
