    Phone is better than expected. Minor scratches to the back around camera area and mild surface scratches on screen. Arrive quickly...package neatly. Great product in terms of refurbished. Will definitely buy again

    I've bought from Rebeelo a couple times and everytime I've gotten a refurbished phone, it always had something wrong with it. Thankfully, Black Market can follow through with their promises of a functional phone. I'd most likely buy from here again

    This is at least my 4th or 5th phone purchase from Back Market. The process has been extremely smooth. Great deals as opposed to buying a new $1K phone. All of my phones have worked flawlessly. (My last Galaxy S10+ had a line on the screen about 1.5 inches down. I should've returned it, but thought I could live with it. It did bother me though!) I've always bought unlocked phones because I don't use a big corporate cell service provider. I really like this S21+ 5G EXCEPT when it boots up it has the BRIGHT PINK TMobile Logo and sound, which I hate (due to bad experience with TMobile in the past)! I think I got rid of all the other TMobile branding like the browser landing page, the ringtone and TMobile app. I don't understand why whoever refurbished this phone didn't re-load a generic OS. All the other reburbished phones have never had any sort of corporate branding. Other than that, I'm OK with the phone, I guess. I still have 28 days to decide. I really don't see that TMobile logo that much, just when restarting the phone so it should be fine.

    I am very happy with my new phone, however my old phone I bought at Walmart, a refurbished moto g pure, and it still had someone's name in it as still having access to the phone, I occasionally got messages from Google asking me if I had just tried to log in , in Dallas, TX, at first I said no it wasn't me, but they put me through the ringer on proving my identity and then after a few new passwords were created in would just say yes it was me, just to avoid all of the stuff I needed to do. so imagine my surprise his name is in this phone as well. I used a c to c cable to transfer my info to the new phone, did I bring him with me? I don't recall using a sim card or not the one from my moto phone. other than that it's telling me that I have malaware and viruses infecting my phone now. I have AVG CLEANING APP, VPN PRITECTION AND INSTALL gaurdio and it well they both say everything is fine, I have so many spam messages and emails I can't l getl through them all. can you help me?

    I Was Very skeptical about ordering refurbished devices but my son ordered me an iPad from back Market last year and I love it it works perfect no problems so I decided to order the Samsung Galaxy S21 Plus so I would see how well it works and give you a review later just received it today November 9th 2023 very fast order because I ordered it on November 6th and 2023 and it said it will be here on the 13th and I got notifications that it was going to be here on the 10th and then another notification that he was delivered at my house on today which is the 9th so I appreciate I really like the service I recommend it to everyone and thank you very good I would recommend you

    This is my second order from Back Market, and again I am in love with my new phone. I first ordered a iPhone 8 for my daughter to test out how I would feel about refurbished phones, as soon as hers arrived I immediately ordered mine. I ordered excellent condition and that's what I received. It's working perfectly.

    I used to get refurbished through eBay. Then this time it was a two-time nightmare. I read a review for Back Market and I'm glad I did. The phone arrived quickly and has worked flawlessly. I will definitely use Back Market when it is time to upgrade again!
