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 pleased with my purchase, Samsung galaxy s21, the phone is light and quiet fast. The camera could have been better. Back market is definitely a place I recommend, between me and family this is our 4th time to purchase a refurbished phone. Great service, fast delivery and communication.

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 am pleasantly surprised! I had just ordered 5 refurbished samsung galaxy a51’s last month on amazon to give to my family in another country. Great price but there were multiple issues with the phone and 3 of them have stopped working. I was extremely sceptical with buying another refurbished phone. My daughter had been researching on this site to look for a phone for me to use. I placed the order yesterday was told that it would come next week but i received it next day! Absolutely fantastic. Straight out of the box it looks brand new, body is clean, no scratches it looks perfect 🥳 Honestly so happy with this purchase, would definitely recommend and i will be buying again soon !
