    Great company and the phone I wanted was in perfect condition, really pleased. HOWEVER, do not trade anything in if you are looking for honesty! I sent my previous phone in having been made an offer. It was in pristine condition, I looked after it extremely well. Once received, the third-party refurbisher offered me a lower amount saying there were dents and scratches. The photos provided were very clearly not the way I had packed up the phone and couldn't have been done in transit - to be frank, if it was even my phone (which I can't be sure of) the photos looked like there were scratches that had been deliberately made in one corner with a scourer or something. Go elsewhere for trade in!!

    Phone arrived well packed, on time and as described. Works a dream. We'd ordered a 'good' condition one, to save money, expecting a few scratches or dents, but the condition is perfect. Thank you.

    Replaced my 32GB phone of the same make and model with a 64 GB and I'm very impressed. Functionality is good, the condition is brilliant and it arrived well before the due date. I was able to replace my original phone which was largely brand new with this phone seamlessly. It doesn't come with the tool to remove the sim so make sure you have one before buying.

    Fantastic service from Back Market, but sadly I feel I have chosen the wrong phone. I loved my old Galaxy S7 and find the A21s far too big and heavy for me, and also having to find the button on the side to wake it up, which seems to hide behind the case cover which is very annoying! I guess as an old bird I'm finding it hard to break old habits and hope I'll get used to it. I'm sure it's a brilliant phone, but just not for me!

    Amazing condition, Good price, Perfect screen condition (pretty much brand new), came with a nice charger and overall I am very happy, One thing to note is my phone did not arrive with a "SIM-CARD" tray but for me personally this was not an issue, very happy with the price I paid & how fast it came.

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
