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.

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 👍

I treated mysel to a new phone last year for my birthday and After a couple of weeks I hated it, it was like a brick but stuck it out as long as I could till I couldn't stand it any more so decided to treat myself again this year. After being a little dubious about refurbished phones, I did some research and decided to go with Back market and so pleased I did its a S21 wasn't sure what rate to go for and settled on good I thought I can live with a few scratches witch hopefully wouldn't show under a case. Wow what a surprise it came within 48 hrs and is immaculate looks brand new. I absolutely love it thank you back market I've recommended you already and will be back 😀 I don't know about 5* I give you 10 🥰

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. 😀
