    I myself have had the A31 for three years and am very happy with it. As with the other Samsung mobiles, it is very easy to use, which inspired me three years ago to recommend this one to my wife after the old mobile stopped working, and she is also very satisfied.

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
