    My first experience shopping on Black Market — and it exceeded all my expectations! To be honest, I was really nervous about ordering the Samsung Ultra S25. But to my surprise and delight, the phone arrived absolutely like brand new, in original packaging — everything was perfect. I saved over £400 — just wow! The device works flawlessly, and I hope it stays that way. But even if something does go wrong, I have a 1-year warranty, so there’s really nothing to worry about. The experience turned out to be so much better than I expected. Also, a big thank you for the excellent customer service — the Black Market team truly impressed me!

    It was my first purchase with BackMarket, after my father-in-law 3rd purchase, I got confidence in ordering a S25 Ultra (the only one available at the time). I ordered it around 11:30am and got it delivered next day afternoon. I am amazingly satisfied and am happy with it.

    I bought S25 Ultra 1TB. This is my first time purchasing from BackMarket. I was really scared but thought give it a try. The product arrived in 2 days. I was surprised excellent quality. Looks brand new. No problems so far. Im enjoying the product. Will definitely buy all my tech from BackMarket from now on. We even have 12 month warranty. Thanks. 5 Stars. Satisfied customer.

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
