Easy to use website, lots of choice. Extremely happy with my new refurbished phone, my second one with Backmarket,unfortunately the first refurbished phone I had wouldn't keep its charge,hence this new one.

This is my 2nd experience with Back Market, delivery ahead of schedule! Getting it up and running went very well. The only downside was that I hadn't thought to order the appropriate protection and I had a lot of trouble finding it!

The product is as described and expected . The service and contact is great . I find shipping with FedEx a bit inconvenient because you have to be at home for delivery. DHL would have worked better for me.

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
