    I'm Really happy with my Samsung galaxy S21 ultra 5G! I really like the screen size, how fast it operates and the long battery life! I'll definitely recommend Back Market to anyone looking for a really good refurbished phone!

    I knew that the Samsung S21 Ultra had a great camera, but the $1100-$1200 price tag kept me from owning one. Along came Back Market with a refurbished one in excellent condition at a third of the price with a one year warranty, so I jumped on it. The photos are outstanding, day or night and I am more than satisfied.

    I was very very skeptical about buying a refurbished phone. I debated about it for months. When my son bought a refurbished iPhone that looked brand new, and worked perfectly I decided to go for it! I was not disappointed! I got the Samsung galaxy S21 Ultra in excellent condition. It came quicker than expected and there were no noticeable scratches or dings on the back, there was a tiny scratch on the screen which you cannot even see with the screen on. Overall I am super satisfied with the phone, I got a great deal on an awesome phone! I will definitely buy from Backmarket again!
