    This is the third item I have purchased from back market. I truly don't foresee ever buying electronics brand new again. The phone came in record time, in stellar condition. You would truly never know it was refurbished. It works great, I have had zero problems with anything I've purchased from back market and the Galaxy s23 Ultra was no different.

    I was hesitant to ordering such an expensive refurbished phone but I have been pleasantly surprised with my purchase thus far. My phone came in better than Good condition. My only "issue" was that when I started the phone it didn't go through the initial start setup. I ended up factory resetting the phone. After setup I had to go through the settings to unlock the network, which is not a big deal but it is something that not many people would know or consider. Aside from that, it has been a fantastic phone that has worked with my Mint plan.

    I only have my Samsung galaxy s23 ultra two days ago (not cheap) but I tell you I'm pleasantly surprised by the quality of the phone. No scratches or dents. Works flawless. My only gripe is you should have included a owner's manual. Quality! Product would purchase again.

    I was skeptical buying a refurbished phone. I chose Back Market because they have a great warranty. I bought a S23 Ultra and it is in perfect condition. It came with a charger. I am happy with my choice.

    A fair deal on a S23 Ultra that looks and seem new if I didn't know better.. upgraded because I had to S20 (also a great phone) broke when I dropped it. I had never heard of this place and was a little skeptical, but I finally read enough to put me at ease. Glad I did. Great Phone, Great Price, Get Company and Refurbisher.

    Fabulous! Ordered Samsung S23 Ultra from Back Market and couldn't be more pleased. Phone arrived promptly and existing number and data including my dozens of apps transferred without any problems as well as all data. Did not include a charger but did include a charging cable. This was described in the advertisement. Phone appears new and works absolutely perfectly. Highly recommend Back Market!

    we were sketchy on ordering at first but after asking around we said screw it and tried it. bought an s23 ultra and so far no bad issues have arrived. I can honestly say. I'll order again from back market.
