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.
