It's my second time buying a phone on Back Market. And only because I smashed the first phone on the floor accidentally and needed another one. The OnePlus9 I got was in great condition, the battery is the only thing that maybe is not great because I have to charge it quite often but the rest is impeccable.

Happy with the condition. Looks new and battery life still good. Some side buttons feel a bit worn, but no worse than I'd expect from a "Good" condition

Ordering process great, speedy delivery although the phone wasn't as good as I'd hoped, cosmetically excellent but the battery was very poor, sent it back within the return period

The delivery was very quick and packaged well. Even though I picked 'Good' quality I couldn't find any scratches and overall the phone was in very good condition. For those wanting to test the battery I would recommend setting the app you use to 'dual cell' to give a more accurate reading. I so far got over 85% battery which was better than expected.
