    I've used Back market for tech over the last 2-3 years now and have always found it to be great. Good choice of products, wide variety of condition and price, something for every budget. Quick service, reliable, even when there's a problem its dealt with quickly and efficiently. I have been highly recommending you to all my and friends. Buying reconditioned products is good for the environment and that's really important to me. 5 star products with great customer service and good for the planet.

    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 🥰

    Bought my first refurbished phone as a gift and got to say it probably won't be my last purchase. The phone was rated as good condition, but I would say it was more in excellent condition. Other than not having the original box the phone was in near pristine, I say near because there was one tiny and I mean tiny imperfection on the casing, but don't let this put you off as I had to look hard to find it!! Well worth the money on looks alone. I can't comment on the functionality because as I say it is a gift so I won't know about that till after Christmas :).

    Well I must say I was a little dubious ordering a refurbished phone but honestly I'm more than happy with it. You wouldn't know it was refurbished at all. I went for the excellent condition samsung s21 and it's perfect and £95 cheaper than anywhere else offering the same phone.

    Arrived quickly. Condition (pristine) was accurate - no marks or scratches. Set-up was fine just like a new phone (fairly easy with Samsung Smart Switch). Battery condition is good - retains charge well. A bargain compared to a new phone - and I prefer to use refurbished equipment as long as the condition, price and technology meet my needs. Full marks (so far).

    First time I've used back market, I admit I was uncertain if buying a refurbished phone was a good move. But with the 12mth warranty felt well they must feel confident of their phones! So I gave it a try, and so far so good. The phone was in an almost as new condition which surprised me and exceeded my expectations. Lots of communication along the way keeping me informed on delivery. I also was able to trade in an old samsung for £43 that I didnt plan on doing. I thought its at least a saving off the price I paid for the new one. So yes was pleasantly surprised and would buy again in the future that offers the chance to buy a more high end phone for a more affordable cost. If I had to make one negative, which really isnt a big issue, the deposit for the trade in takes upto 6 working days to go into a bank. But as promised I did receive the funds within the 6 working days. Otherwise, yep, liked everything.

    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!

Benefits of buying a refurbished Samsung Galaxy S21


At Back Market, customers save up to 50% off compared to the price of new on certified refurbished Samsung Galaxy S21 models. The best part is, you don't have to sacrifice performance quality in order to save money; all refurbished devices on our marketplace have been fully reconditioned, cleaned, inspected and tested to the same standards as a new one. This is the biggest difference between buying a used or second hand Samsung Galaxy S21 compared to a refurbished one.

Buying a reconditioned Samsung Galaxy S21 is also an environmentally friendly option. A refurbished Samsung Galaxy S21 is often a second hand device that has been restored and updated to meet manufacturer standards, which means you'll be helping to keep old Samsung Galaxy S21s out of our landfills, reduce electronic waste, and minimise your carbon footprint.
