Verified purchaseAlways feels good to buy a refurbished product that's been given new life vs a new one. The phone itself is great, but the battery life is less than average. Otherwise no complaints.

Verified purchaseI recently snagged the Samsung Galaxy S21 5G from Back Market, and it's been a game-changer. This refurbished gem looks and feels brand new, and I couldn't be happier with the experience.

Verified purchasePhone is a described which is excellent condition. I have switched everything over from my S8 and all is working perfectly. I was very skeptical about refurbished but after doing some research I decided to order. I am very happy with my phone and will look for other refurbed items.

Verified purchaseBeing my first time buying from Back Market, I must say so far I'm impressed. I've just received my phone, s21 5G phantom violet, and it is only fair condition or so it says I can't not see any marks whatsoever. I will not get to connect it until I get to T-Mobile tomorrow so I will fill you in on the rest after I get hooked up to service but so far so great and if all goes well after activation, I will never buy a used phone ever again 😁 Only refurbished from Back Market 😀

Verified purchaseThe truth is true. I don't know. This was a gift for a friend so I would like to guess no as soon as I get. Whenever she let me know how it worked. Okay, thank you, and I'll be buying more stuff from you guys. I enjoyed the other phone, though. A little

Verified purchaseItem was in great condition! No issues with putting in sim card to start using it right away. Battery life a little dissappointing but still lasts lot longer than my crappy iPhone. I did see this phone on amazon for a little more but i dont trust them checking the phones to confirm they have no issues like you guys do on this site. Extremely satisfied and excited to use this site for another purchase soon!

Here’s what you help prevent on average by choosing a reborn smartphone over a brand new one.
That's like driving an SUV from NYC to Chicago.
That’s around the weight of a baseball.
That's like 20 dogs digging in your yard for a week.
That's like running a faucet for 3 days
