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 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.

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.

Good overall condition except that the phone's minus button doesn't work. It would deserve a small gesture from your part..
