I recently purchased a refurbished Samsung Galaxy S21 Ultra in excellent condition from backmarket.co.uk, and I couldn't be happier with my decision. The device looks and functions like brand new, and I got it at a fraction of the original price. The service was exceptional, with fast shipping. I highly recommend buying refurbished electronics from this site, and my Samsung S21 Ultra is a testament to the quality and value they provide. It's been a fantastic experience, and I'm thrilled with my purchase!

I really love the phone and everyone attested to the fact that if i hadn't mentioned its refurbished, they wouldn't have know due to it excellent outlook, affordability and payment structure. Back market has won my heart!

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.

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 😁

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.

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

After I've last week bought this, so far I'm pretty happy with this buy. By a highly competitive price, I bought this Samsung galaxy s21 ultra 5g mobile phone which made me very happy. Thank you very much 'Black Market'.

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

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
