    Product was as advertised. High quality product (I had chosen for the Premium grade) and very prompt delivery. I have been using this for a couple of weeks and the battery life is very good as of now (it does not give me the feeling of using a refurbished phone). Very happy and will definitely continue to consider in future for electronic products.

    I was somewhat sceptical about buying a refurbished phone having never done it before. However, thought I'd give it a try. I went for the fair grade phone expecting scratches, dings, marks etc all over it. My only want was the screens to be good enough, as I was planning on putting a case in anyway. The phone, however, is immaculate. I don't know how this is a fair graded phone, because it looks like new! I can't imagine how the higher grade phones look, they must literally be as new. Seriously happy with my purchase and glad I stuck with the fair graded phone. Would highly recommend to anyone.

    I am delighted with the phone itself and the colour which I love. The only problem I encountered was when I set up the phone, there was a link that I clicked ((unfortunately I cannot remember where), and it made me reset the phone as it mentioned I was malware/spam after that moment. It is working safely and effectively because I downloaded the security software first, thank you.

    The phone came way earlier than expected and in a very good package. Yes, the online description said it’s fair, but I was surprised it came like looking like a new one…and it works and feels like a new one too. I’m very pleased 🥹

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
