Second-hand device received in 3 days. I ordered this Oneplus 9 to replace mine which was malfunctioning because I wanted to keep my ergonomics (I have already replaced the back of my various Oneplus myself on 3 occasions, it's easy)... Paid around 164 euros and works perfectly. I'm just thinking of having the battery replaced as it's struggling to last a day with intensive internet use. This is the 4th time I've ordered from BackMarket (2 Iphone 6S, 1 Samsung and this Oneplus) and I've never had any problems. So I recommend it!

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 👌😉

Functional as new. However, I was expecting a less damaged phone in appearance given that I had taken a phone in "very good condition. But that doesn't seem to have any impact on its operation.

The phone I received after returning the first one works perfectly. But it's clear to me that the first shipment was an attempt to pass on a phone with a non-original part, which the seller could not ignore. This has left me with a bitter taste.
