Was kind of worried about a refurbished phone.Ordered the Samsung S21 ultra in very good condition. It came in 3 days. To my surprise it was in excellent condition. Stuck in sim card and fired it up and is running like a champ.Back market you have me as a customer forever.

Hello. This is my first time ever ordering a refurbished, well, anything! So needless to say. I cautiously ordered a Samsung S21 Ultra after reading through many reviews. Boy was i nervous. Not because of the reviews, but i was a mere virgin at this. All i wanted was an ultra with a snapdragon processor and screen and camera unblemished. And then there are the fakes i hear about. $450 on the line here. But i was absolutely blown away and on my children, i am not a bot but i ordered early morning and my phone arrived by the end of the next day. Back market made my freaking year! Im a 5 star satisfied,and from now on persisting customer. Thank

Phone is basically brand new. Which i did get in excellent condition and it shows it is. Doesn't even look like a refurbished phone. Connected to my service once we got it all figured out. Will definitely come back here for upgrades. 10/10.

I am very happy with my purchase of the Galaxy S21 Ultra. The phone is refurbished however its difficult to tell by how clean and in good condition it looks. I am very much satisfied with my purchase.

Got exactly what I ordered!! No hassle easy to set up! Perfect condition screen, only wear was a TINY TINY TINY scratch on the corner of the hosuing, as I plan to use a case this is not a problem whatsoever, also it IS a refurbished product with that in mind nothing could have gone better it even got here earlier than backmarkets estimate!

Just received the phone on the 15th after ordering it on the 11th, so Id say the turn time and shipping logistics to actual possession of the phone via FedEx was outstanding and it was free!!...Bought a Excellent rated phone...Samsung S-21+...Phone was in outstanding pristine condition with a 85% charge to the battery...after inserting the carry-over SIM card, it fired right up with zero defects and I had telephony capabilities immediately along with data supported with a strong 5G signal, after going through the phone, I determined that everything worked as it should or supposed to!!...Only thing that was a bit annoying part was that it was about 20 updates behind, and literally spent a half a day letting it catch up with updates!!...Noteing that's NOT Back Markets fault, just Verizons protocol, the audio's insane and the picture and movie capabilities with this phone are beyond amazing with so many options it would be too long to list, the capacitive touch interface is snappy and crisp, with great telephone sound when talking on it!!...Over-All The entire purchase and product was the best phone purchase experience I've ever had and extremely satisfied with the results...I will de ...
