I recently purchased a refurbished Samsung Galaxy S21 Ultra in excellent condition from backmarket.co.uk, and I couldn't be happier with my decision. The device looks and functions like brand new, and I got it at a fraction of the original price. The service was exceptional, with fast shipping. I highly recommend buying refurbished electronics from this site, and my Samsung S21 Ultra is a testament to the quality and value they provide. It's been a fantastic experience, and I'm thrilled with my purchase!Galaxy S21 Ultra 5G 128GB - Silver - Unlocked - Dual-SIMPurchased on the 20 October 2023

The item I received although it was shown as good condition was excellent, no visible marks on both the screen and the body and back of the phone. The purchase of the phone was hassle free and easy and the delivery was excellent with the phone well packaged for safe transit. I would definitely recommend buying from this company saving yourself lots of money compared to a new phone, however as already stated you wouldn't know the difference between new and refurbished.Galaxy S21 Ultra 5G 256GB - Black - UnlockedPurchased on the 20 September 2023

Phone arrived with the bottom corners scratched, the screen itself was mildly scratched as well which is to be expected from a refurbished phone. Functionally, the phone works as expected, however battery life is abysmal. I was hoping the phone would've arrived with a better battery condition.Galaxy S21 Ultra 5G 256GB - Dark Gray - Unlocked - Dual-SIMPurchased on the 24 November 2023

I bought this phone for a better battery, there isn't much difference to my previous phone s20. However, everything else works perfectly. Really happy with my purchase, you couldn't tell it was a refurbished phone. Thanks Back Market 😁Galaxy S21 Ultra 5G 128GB - Black - Unlocked - Dual-SIMPurchased on the 28 March 2024
