    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 😁

    My first time ordering a refurbished phone, heard of back market and thought I'd give it a try. Ordering and receiving very smooth. Ordered a "good condition" phone it really looks brand new and is in excellent condition I will use this site again

    Phone was delivered in impeccable condition, honestly looked brand new! So pleases I discovered Back Market and saved myself so much money without compromising on quality. Highly recommend to anyone who's wanting to buy a new phone as you would never tell the difference that you're getting a refurbished phone.

    Galaxy S21 Ultra 5G 256GB ordered, excellent condition paid for. Phone screen and case are fine and have no issues, the phone looks pretty much brand new. Had it for 2 weeks now and running AccuBattery Pro app to check battery health, currently at 88% following a few full charges. Better than expected. Overall I am very satisfied with the phone.

    Phone arrived with the bottom corners scratched, the screen itself was mildly scratched as well which is to be expected from a refurbished phone. Functionally, the phone works as expected, however battery life is abysmal. I was hoping the phone would've arrived with a better battery condition.

    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

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
