    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!

    Great phone! I was a bit reluctant getting a refurbished phone but did not want to spend the amount of money the phones with this camera and storage are. It was a bit bigger than I expected but it's not an issue and it looks brand new. The only downside is the battery life. i have to charge it daily, which is what was annoying me about my previous phone. All in all it's great if you don't mind daily charging

    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.

    Came at a good time, 2 scratches on screen that are barely noticeable, bought fair anyway so it was expected. Scuffs around the side of the phone, but easily covered with a case anyway. Phone works perfectly fine, no problems with software and battery is working decent. Not amazing battery life, but not abyssmal. Not much expected for a refurbished, but it should last me a while. Go for it if you want a cheap phone at a good deal.

    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 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.

    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!

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
