My previous phone packed up after several years. As I wanted to stay with Samsung S, getting to a reconditioned phone made sense as the price wasn't too much and the phone is great. I highly recommend using Back Market!

This is the second phone l've bought so l had high expectations. I was not disappointed! Another fast delivery and a phone in what looked like perfect condition. I'm so glad l updated and l love my Samsung Galaxy S 21. I updated mostly for the camera as l do art/ use my phone camera a lot..what a difference from my old phone. I would buy from Back Market in future again, confident l'd be getting a great service/site to buy refurbished tech.

I was looking for a replacement of my old samsung s6, I had seen back market advertised & as I didn't want to splash out for a brand new phone I gave them a try.I was a bit apprehensive about buying a refurbished phone but I needn't have worried.Phone I ordered was samsung s21+ in excellent condition & that's exactly what it came in,not a mark on it & even has original protective film on front & back,battery was at 78% but soon charged up to 100%, very well packaged & excellent delivery.Thanks back market one very happy customer 👍 10/1

Reviewed in United Kingdom on 19 December 2023

Well to be perfectly honest I'm quite disappointed when I compare my previous experience with buying excellent condition refurbished phones. The phone that was sold to me turned out to be from US market which means it does not fall under Samsung repair service in UK (they can't fix it, if it breaks). Additionally, I found some dust inside the camer lense for selfies which suggests to me a broken seal when someone cleaned the microphone. That means the phone no longer meets the IP68 standard. It is most likely no longer sweat/fog/steam/dust/moisture proof. I suppose 4 stars are for how clean and scratch less it was and the nice person from your service! Sadly I had to send it back for replacement.

I recently purchased a refurbished Samsung Galaxy S21 Ultra in excellent condition from backmarket.co.uk, and I couldn't be happier with my decision. The device looks and functions like brand new, and I got it at a fraction of the original price. The service was exceptional, with fast shipping. I highly recommend buying refurbished electronics from this site, and my Samsung S21 Ultra is a testament to the quality and value they provide. It's been a fantastic experience, and I'm thrilled with my purchase!
