Prior to ordering 2 Galaxy s20 ultras from Backmarket I ordered the same refurbished phones via an Amazon partner. Both these phones had faults whereas the Backmarket ones work perfectly. They were delivered promptly and are in great condition.

In a bid to gift my wife a birthday surprise, I ordered Samsung Galaxy S20 Ultra 5G 128GB for her, which she turned out not to like because it didn't meet her expectations. However, the phone was neat and nice except that the battery wasn't so great. I also expected the camera to be superb, being 108mp, but surprisingly, it didn't meet my expectations. As a result of this, I had to return the phone, and I must say the whole process was seamless and remarkable. My customer service experience was quite outstanding.

The item arrived with in the allotted time period, but there was problems with it. Before I mention them I would like to say that Backmarket was shift to address the issues and arrange a replacement or refund. I could only make calls using a set of USB c head phones as no sound was heard from the speakers and on audio input with the built in Mike. I am waiting for conformation of a replacement unit which at the moment is being dealt with swiftly.

Ordered Galaxy S20 Ultra 5G listed as excellent condition. Truly, there is not a mark on it. It arrived a day earlier than originally estimated and Backmarket kept me informed the whole way through the process. I've never bought a used phone before, and was a bit worried but I'd like to reassure anyone else that product quality and customer service are second to none.
