Bought a Samsung s25 ultra 512gb model, device was delivered earlier than expected, opted for the good condition, which came and was in excellent condition with limited signs of use. Battery health was 99%. Colour requested was blue-silver but appears more on the white side, overall would definitely use again for future purchases.

I was genuinely surprised. The phone is practically brand new. Not a single mark or scratch anywhere to be seen. Did a battery health check which showed 100% battery health, I was not expecting that. I basically got a new phone for £700 less than buying directly from Samsung. Very happy. Will be using Backmarket again.

I was informed that the phone would take 3 days for delivery. In fact it arrived the following morning after the order was placed. It was very well packed and inside was the Galaxy s25 Ultra phone, usb cable and SIM card tray opener. The condition was as good as a brand new phone. No marks, scratches or screen blemishes anywhere and it was fuly charged ready to go. Some reviews state the phones are not UK region This phone is definitely UK region it's accepted all of the data from my old device including social media apps and WhatsApp. I have downloaded all Samsung software updates and installed them with no issues. It is operating exactly as it should do. Thank you Back market for the excellent service and an amazing phone. You've certainly convinced me that buying refurbished is the way to go in the future.

I am really pleased with my phone, it was in immaculate condition when I received it and so much cheaper than buying a brand new S25 Ultra. The battery life is great too and fast charging is extremely fast too. I have upgraded from an S22 Ultra which I had for 3 and a half years. The battery was never great on the phone but I knew that when I bought it as I wanted the phone for it's camera. The S25 Ultra still has a great camera and 512GB is far superior to the 128GB on the S22 Ultra. The reason I upgraded was because my phone had no storage space available and the battery was not efficient anymore. The S25 Ultra is a great phone, easy to navigate and has lots of better features on it. I would definitely use Back Market again to buy a reconditioned phone. They have great reviews on Trust Pilot too. I purchased the phone around 11pm on a Thursday evening and it was due to arrive on the following Tuesday. The phone arrived on the Saturday afternoon, I received communication to let me know when it would be arriving too. Very quick postage, I wasn't expecting to receive the phone so quickly. Thank you very much.
