I've been really impressed with the Galaxy S25 Ultra. The performance is excellent, the battery comfortably lasts all day, and the display is outstanding. The camera system is a significant step up from my previous phone, producing fantastic photos in a wide range of lighting conditions without needing to understand lots of camera settings. The S Pen is a useful addition, and the overall build quality feels premium. Despite having so many features, the phone is straightforward to use, which is something I particularly appreciate. Buying a refurbished device was also a great decision. The phone arrived in excellent condition, looked virtually brand new, and performed exactly as expected. It's reassuring to know I've saved money while also making a more environmentally friendly choice. Overall, I would highly recommend both the Galaxy S25 Ultra and purchasing a refurbished model. It's an excellent phone and represents fantastic value for money.

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'm extremely happy with my experience with Back Market. I bought a Galaxy S25 Ultra in Premium condition, and it arrived looking almost brand new. The phone works perfectly, the battery is excellent, and I'm very pleased with my purchase. I also traded in my old Galaxy S21 Ultra, and the whole process was smooth and honest. The assessment was completed quickly, and I received exactly the amount I had been offered. The payment arrived very fast. Buying and trading in through Back Market was easy, professional, and stress-free. I would definitely use them again and highly recommend them to anyone looking for quality refurbished devices. Thank you! 😊
