    Excellent quality and delighted I had the choice of a new battery which is not on offer in other refurb websites I visited. Very happy with my purchase and will be back.

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
