    This is a fantastic phone and I totally recommend it. I was initially skeptical about buying a refurbished phone but I saw all the positive reviews and decided to give it a shot. I went for the "good" option just to be safe and I was totally satisfied with my purchase. The phone looks new with an unnoticeable scratch at the back. Other than that, it is totally worth it. I'm enjoying the phone. Thumbs up to the Back Market for their excellent customer service. I will surely come back for more. 😊

    I bought this phone for a better battery, there isn't much difference to my previous phone s20. However, everything else works perfectly. Really happy with my purchase, you couldn't tell it was a refurbished phone. Thanks Back Market 😁

    It's in a great condition, almost like a brand new phone. Gave it to a couple of friends to tell if it's new or refurbished and all of them said it's new. In general, this was a great deal

    I can't really say how good the phone is because I will be using it as a back up phone when I move to the philippines in march. But it looks like a brand new phone not refurbished.

    3.5/5

    The order process was easy and a lot of info about the product. After 10 months of buying the Samsung S21 Ultra 5G it started dying on me. I couldn't get it to switch on even when charging it, so I sent it back to the seller and they were unable to fix it. I got a full refund and this was communicated to me well.

Reborn vs. brand new

Here’s what you help prevent on average by choosing a reborn smartphone over a brand new one.

77.3 kg of carbon

That’s like driving an old banger from London to Edinburgh and back.

6.3 oz of e-waste

That’s around the weight of a baseball.

537.1 lbs of raw materials

That's like 20 dogs digging in your yard for a week.

77,000 litres of water

That's like running a faucet for 3 days
