    The Samsung S21 Ultra appears to be fine in the two weeks since we received it and was as promised. Ordering was easy and delivery was as expected. Our trade-in offer was much lower than we had anticipated ($25.00) for a phone in complete working order without problems. I have previously purchased certified, refurbished smartphones directly from Samsung and felt we received a much better & fairer trade-in offer. While the price of the S21 Ultra was cheaper from Back Market, I believe that I might have fared better buying from Samsung in terms of overall cost. I will research more closely when it's time for our next purchase.

    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!

    I was very skeptical about ordering a refurbished phone. However, my son convinced me to order him a galaxy s21 plus and surprisingly, it was great! No issues. Looked brand new. Fast forward to me breaking my phone. I looked and found the s21ultra and ordered it. These phones are definitely top notch! I have no issues what so ever with

    I was a bit skeptical about getting a refurbished device, but so far it’s been almost indistinguishable from the experience a new device would have given me. Though I chose Backmarket specifically for their 1 year warranty, so we will see how it holds up over time. But for now I’ve had no issue with it yet apart from needing to reset the Bluetooth once because it stopped connecting to my car. Though that might have just been caused by interference. Have not had it happen again yet.
