    First time buying a refurbished phone and will continue to by refurbished. . . . . . I have been using the phone for a while now and it is next to new, I am very happy with it and I will be consulting Back Market should I need any other devices. I would highly recommend!

    I love my new phone, it really does feel brand new. Being able to go sim only will halve my phone bill. The whole process was very easy, have recommended Back Market to several people already. No more massive bills, delighted

Renewed vs. brand new

Here’s what you help prevent on average by choosing a renewed 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
