    Hi I am really happy with the phone. There was just a small screth but really not a big deal. The phone works perfectly, it came really fast. I like a lot the screen, it reacts fast and the colours are pretty good in the screen. I bought separately the OnePlus 9 charger, and my phone charges in 30min. Sometimes the battery holds one day and a half or so, by normal use. Very happy.

    This is the fourth phone I've bought from backmarket and they've always been so fast and responsive - well done! The only downside is that the carrier wasn't able to deliver on the day, and I'll never know why. I recommend 👍👍

    - Packaging small cardboard minimalist but effective and sufficiently protective. the phone was well fixed 👍 - The phone announced in very good condition is actually in excellent condition I did not find a trace or a scratch. Android 100% functional speed of the system, photos, the 4k 60 and 8k 30 are really effective, and the battery the same, 1 month of intense use and shares co on the move and it still tjr easily 1 day and a half see 2. I've been using the One+ since the 5t and I'm telling you, you can go for it with your eyes closed 👌😉

    I bought it in "good" condition, expected some scratches but I can't see any scratches, or I'm mega blind. All the better :D Delivery and everything super and fast. Can't complain :)

    Great mobile phone and extremely fast, reliable delivery. My delivered mobile phone is "only" in good condition, but it actually feels very good. 0 scratches, neither on the display nor on the outside. I am very satisfied and would definitely order again.

    Phone arrived today (2 days before estimated) this is my wife's new phone, and she is very happy, as it looks in perfect condition with no sign that it was pre used. The phone also arrived with 75% charge so she was able to set it up immediately. Complete process took her about an hour and everything has been transferred from her old phone and all is working. A very happy lady now.

    Product itself very good. Delivery with ups was terrible, I was supposedly not there twice even though I was at home, no call was made. Had to phone them and complain to get the parcel delivered.

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
