It'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 👍

The phone was excellent, it exceeded my expectations. I previously bought this model from you for my wife and this one is to the same high standard. I'll certainly buy from you again and wholeheartedly recommend you to prospective buyers. A well deserved thanks.

I 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!

Condition said it was fair but its near on perfect. Bought for my mum who is in her 80s, easy for her to navigate her way round and easy for her to use. This is the 3rd time buying from this site, wouldn't buy phones from anywhere else now. Thankyou. 😀
