I keep getting compliments on it! It's a fantastic phone with a stunning processor and camera. Bought in fair condition, but honestly looked good as new. I bought my last phone refurbished as well and never had a problem with it and this one is just as good.

Phone looked brand new. Functions just like a brand new phone. I was definitely skeptical about spending this much on a refurbished phone, but I couldn't even tell. I am so happy with the color as well even more beautiful in person!

My S21 Ultra arrived quickly. I still don't see a scratch on it or anything showing that it's refurbished. I bought it in good condition but it seems excellent to me! I was very satisfied with my purchase and the communication from Back Market. Two thumbs up!
