    Phone arrived today (2 days before estimated) this is my wife's new phone, and she is very happy, as it looks in perfect condition with no sign that it was pre used. The phone also arrived with 75% charge so she was able to set it up immediately. Complete process took her about an hour and everything has been transferred from her old phone and all is working. A very happy lady now.

    Bought my OnePlus 9 here, it was described as "fair". It arrived super quickly, 1 or 2 days before the announced delivery date ! Even if the condition was described as "fair", the phone looks almost brand new apart from two micro scratches on the screen, barely visible. It works like a charm, super smooth and fast Android phone, quite life changing from my old iPhone 6 hahaha. The battery is great as well, overall an amazing purchase, thank you Back Market's team !

    The Phone is great , no scratches or marks but had to do a system update to stop it overheating . all the apps work well and it was simple to transfer from my old phone. The delivery and the packaging basic but fit for purpose. over all very pleased , I would recoment it.

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
