Fantastic deal and quality phone. Was a much need upgrade from my ipohone 7, which this feels like a smartphone gone light speed! Couldn't tell it was refurbished as screen was great, phones great and the battery life is very good - got mine in "excellent condition" so can't comment on other grades 😀Galaxy S23 Ultra 512GB - Black - Unlocked - Dual-SIMPurchased on the 21 November 2023

Fast and hassle free delivery, phone arrived well packaged and in excellent condition. Great communication from the Back Market team, already recommended to family and friends to purchase refurbished tech in future and buy from Back Market, you'd be mad not to!Galaxy S23 Ultra 256GB - Black - UnlockedPurchased on the 16 February 2024

Came very quickly. I've had refurbished phones before but always ordered fair condition. I ordered this one in excellent and was in immaculate condition. I've been using the phone for around 3 weeks and I've had no issues. XxGalaxy S23 Ultra 256GB - Beige - UnlockedPurchased on the 1 March 2024

Fantastic experience with BackMarket. First time I'd bought a refurbished phone and it was a great success. The phone is in exceptional condition, looks the part and functions at 100%. I was concerned about the battery life but the phone exceeded expectations and for a fraction of the price. The red colour makes it unique and very glad to try out BackMarket and will definitely buy more of my electrical needs/goods through this site! Would highly recommend!Galaxy S23 Ultra 256GB - Red - Unlocked - Dual-SIMPurchased on the 10 March 2024

I bought a refurbished s23 ultra in good, and the phone is perfect, I really couldn't see any marks on it, but that wasn't an issue as I always use a case. But when the time comes I will buy from back market again.Galaxy S23 Ultra 512GB - Grey - Unlocked - Dual-SIMPurchased on the 31 March 2024

Am very happy indeed with my S23 ultra. Looks and feels like new. No scratches or marks. Had for a few weeks now, and all appears to be working perfectly 👌 Was worried about buying my first refurbished phone, but the 30 day returns policy swayed it for me. Will return to Backmarket when I'm ready to buy again.Galaxy S23 Ultra 256GB - Green - Unlocked - Dual-SIMPurchased on the 12 February 2024
