Okay, so. . . customer service acted professional in most cases except one, they had great communication, they were prompt in replies and were courteous but i'll get to the negative issue at the end, The phone iteself came very quickly in the post, great job there, and it was well packaged, The quality of the phone state, when I looked at the screen, it was very impressive for a second-hand phone, it looked brand new, no scratches, and when I turned on the phone, it looked even better, Now the negative customer service issue, Before buying the smartphone I asked the customer service agent for the exact android version of the phone, they replied that it would be either android 9 or 10, I said can you double check it yourself or with the seller? They said no we can't, I said if it's android 9 or 10 that's fine but I don't want it to be android 11, they said it would be 9 or 10, And when I checked the version after turning on the phone, it was 11, Now, because i'm tech savvy, I was able to modify the phone and install android 10, but here's the thing, most people would be pissed if they asked to have a specific version and not to have another version, only to find out that they get the version they don't want after paying nearly €200, and I was pissed off, but lucky for you, i'll let it go, But it is drastrically poor service from 'Back Market' that they can't do a simple thing for the customer and check and give the correct android version of the phone (the current one, not the stock one), So I advise you 'Back Market' if you want more business and more customers and also to keep customers, that problem needs to be fixed, pronto 4 out of 5 stars, you lose a star for the issue mentioned, which could be easily rectified for new customers and purchases, Thanks

I bought OnePlus6 in "very good" condition. The reality is that the phone looks brand new. The battery is also in excellent condition. Eco-friendly packaging + usb cable and sim card removal spender. Delivery very fast, ordered on Friday, delivered on Monday. For me great satisfaction. Thank you

Everything seems to work and even if the product is just in a "Good" condition looks as good as new. I will see if anything happens with it. But I would still recommend since they are all cheaper than a brand new one and you can barely notice a difference after a while since it'll wear out anyway 👌

I like it, but the battery doesn't hold its charge. This is a real shame as I like the size, the way it works etc. I bought it to replace my old phone which is starting to have a weak battery, but unfortunately it lasts longer than my new OnePlus 6. I will have to return it to you.

Bought this One Plus 6 in order to install Linux on it to experiment and test the state of linux on smartphones in 2024. The product photos therefore show it running PostMarket OS, not OxygenOS-Android. About my experience with BackMarket: Sometimes difficult to know where the package is, and the box is much too big compared to the contents. However, in my case the phone was well secured in the box and therefore protected from shocks, contrary to what you might hear from other reviews. Concerning the condition of the phone: The phone is in excellent condition, I have the impression that it is as good as new. It came with a charger, which is probably not the original one, but it works. Before installing Linux on it I obviously quickly configured Android (Oxygen OS in the case of the One Plus) to install BackMarket and do the tests: everything worked. I didn't test the battery under Android because I was impatient to start my experiment, but under Linux, without using the laptop (in standby) the battery lasts much longer than 2 to 3 days. Regarding my experience with Linux : I was able to install linux (postmarket OS) on it without any worries via the web flasher after unlocking the BootLoader, as the One Plus 6 is one of the best supported laptops. I was worried that I might have hardware problems if the parts had been changed during the refurbishment, but that doesn't seem to be the case. The camera doesn't work under Linux, I should point out that it worked perfectly under Android and that it was totally expected that it wouldn't work under Linux. I'm sure there's a way of making it work, but I haven't had time to do any more tests yet.

Everything is nice! The condition is not just "very good", it's extremely excellent! It was almost impossible to find traces of usage! The only problem is a weak battery, but I understand that it could not be a new one for such an incredibly low price.

It looked newer than I expected. The only problem is the battery, but it was already mentioned, so I knew that when I was buying the phone. Overall, it was an excellent purchase.

Received in very good condition, with a scratch-free screen and only a few scratches on the casing (which in no way hindered use). I unlocked the bootloader very easily and installed PostmarketOS, I recommend it!
