4.6/5It'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.

5/5Happy 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

5/5The 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.
