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.

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!

Second order from Backmarket (my previous one lasted 4 years and 8 months). The new one is in perfect condition. I will continue to order from here.

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

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 👍👍
