    Excellent phone. I purchased as condition 'good', and I would not expected more if I had selected 'excellent'. The only thing I think should have been done before shipping was 'factory reset'. There were some pieces of information that belonged to the refurbisher, and should have been wiped for the best startup experience. I did the factory reset, and phone behaved exactly as new out of the box.

    Really happy with the quality of the phone and the quick shipping. Aside from a bit of dirt and dust caught in the edges, its pretty much flawless. There is this weird darkening of the screen on the top left corner but it only appears when looked at from a certain angle and doesn't show up during regular use (or gets blocked by the notification bar). Battery health is in pretty good condition too at 90%. I'll admit, I was pretty anxious about giving refurbished phones a try but it honestly couldn't have gone any better. Would definitely buy from this seller again!

    I was skeptical about purchasing a refurbished phone. But I was glad I did purchase from Back Market. The transaction went soooo smooth from the purchase to getting it hooked up to T-Mobil. Best of all the price was right! Thank you so much...I would recom mend u guy's to friends that are looking for a new used phone. Ronald Hom

    The phone functioned with the exception that it would not recognize the SIM. It was like new cosmetically. This is the 2nd phone that did not work with ATT. Nobody was able to help to make either of them work. The refund was timely both times. I have given up on refurbished phones though. I bought a new one instead from ATT that worked out of the box and with a trade in I spent 1/3 as much for a newer phone.

    The Condition i pick was good and the phone came in like Brand new and it charged up with no problem so my first time on this website buying was great and i will keep buying more product from Back Market. 1 thing i do know is the reviews are very important when buying any item from here so for those who are afraid to buy from here its a safe site to buy from and the 1yr warranty is a plus so you don't feel like you got screwed, the seller i bought from had great reviews so i decided to give it a try. Galaxy S21 Ultra 5G 256GB - Black - Fully unlocked (GSM & CDMA MINT Condition when i got it. Deal with them People.

    The phone was in great shape, as always. Saved me a ton of $$$ by buying it refurbished. I am so glad I did.

    Hi, sorry for the delay, had to test the phone out a while before I commented. I'm a person who doesn't like spending a lot of money on electronics with how they get replaced so fast with newer technology. BUt I hate phone shopping and decided to spend the extra money getting a phone that was newer longer in updates and what-not. As expected via the condition rating it said it had (minor scratches on screen but not visible while screen is on) I'm pleased with the condition. The sound is great, the camera is great. The battery I'm thinking is , but I haven't had sufficient time to test how long it actually works for. So far I really like the phone. Thank you 😊
