4.9/5It's like brand new I couldn't find a single mark. Straight forward to use. The only thing is the battery It's not new didn't have the option at the time so doesn't last long. Overall very pleased definitely recommend Back Market 👍

5/5phone was in great condition looked like a new phone and I liked the colour only draw back was after setting it up had to give it at least 8 software updates now phone is working like it should but I would still buy another phone from this company if I needed one their alot cheaper than some of these shops that sell used phones

4.4/5I was a little nervous to order a refurbished phone but I've gotta say this honestly feels like brand new! There's only minor signs of wear and tear on the main body but other than that it's pretty much perfect!

4.6/5Great Service. The first phone that arrived had something very minor wrong with it. I got on the app and within minutes they agreed to replace it with another. it arrived the next day. I didn't have to send back the original phone until I received the replacement, so I wouldn't be without a phone. Very happy with Backmarket

4.9/5Fantastic. Delivered quicker than date advised and although the product was said to be in fair condition, I would describe it as excellent! Have used back market a couple of times now and have advised others to do the same.
