I was apprehensive about purchasing a refurbished phone for my daughter but shouldn't have been as their simple condition rating allows you to decide to save some money if you're ok with a couple of minor imperfections or a fair price for a very good condition product. From description on the website through the buying process to delivery and even just checking in with you a week or so after receiving your order to make sure that you're happy with everything is brilliant. The phone is a Oneplus 6 and is in mint condition and working perfectly. Would highly recommend Backmarket and will definitely be using them again.

I'm happy to say that the physical condition of the device was better than expected and my worries about the battery life were unfounded! I understand the reason behind the minimal packaging and, in some sense, even loved it. But I wouldn't mind having another layer of protection for the device. In summary, great value for money! I hope to use this phone for a long time.
