    Prior to ordering 2 Galaxy s20 ultras from Backmarket I ordered the same refurbished phones via an Amazon partner. Both these phones had faults whereas the Backmarket ones work perfectly. They were delivered promptly and are in great condition.

    Would definitely recommend Back Market, the service was amazing phone arrived within 24hrs of ordering and delivered by DPD. The phone was in excellent condition, was as described. Being my first time order a refurbished phone I went for the best one, and was not disappointed. The phone came with a phone case, nice little touch. When I next require a phone, Back Market will be my first call.

    I was very pleased with my galaxy S20 Ultra 5g (dual sim). It is my first smart phone and I am 77 years old. I am learning how t o use it. The dual sim will be used when abroad with family. I like the large screen for reading. It is in perfect condition and a reasonable price.

    Ordered the S20 Ultra in excellent condition, arrived earlier than the delivery date said, the phone is in immaculate condition, not a single mark on it, has great specs, however the charger port on the phone is a bit dodgy and only charges if the wire is in a certain position with a bit of tension, but that doesn't bother me because I use wireless charging. Recommend Black Market to my mate as he's looking for a new phone. Overall, 10/10 everything and a satisfied customer. Will definitely be returning to Black Market in the future. 👌

    Great service , quick delivery, phone in good condition it's just a bit quiet on calls,I think it may be due to the screen replacement, but I can live with it, the price was competitive, will use again.

    Very pleased overall, delivery was very quick, packaging very good and arrived in very good condition. I did take a gamble with Backmarket and it paid off for me on this occasion. Will use again if I need a decent 2nd phone again.

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
