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. 😀

Fantastic. 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.
