    Ordered a "Good" quality Samsung Galaxy S21 Ultra 5g phone and surprised as its almost like a brand new phone apart from a few cosmetic dints which were expected I suppose. Still to find out how battery performs over time but my wife is quiet impressed with the phone. Would definitely buy another phone from here as they've kept the word on quality of the phone. Keep up the good work and help the planet.

    I ordered samsung s21 ultra,and it comes in very good condition. There are no scratches on the phone at all. It works like a new one . I would recommend to everyone it's better to buy refurbished on a half price than pay full price at store for a new one.

    Needing a new phone and the cost is too much. Well look no further than Black Market. Ive just purchased a refurbished S21 Ultra 5G 128GB from them. I went for their good option and if this is their good option, goodness knows what you get for their best option. This phone was unmarked, charged to 80% out of the box, came with a case and lead. It`s fast, it`s reliable and it ticks all the boxes I could want from a phone. Excellent service from them. Know where I will be heading next time I require any communication device.

    I'm going to be fully honest. For a refurbished phone, the quality is absolutely surreal. No one could tell the difference between this excellent quality phone from back market and a brand new phone. I am completely satisfied and hope to shop again on this website. Back market is seriously outstanding from other stores, easy 5 stars, completely thrilled about the quality.

    Great service and massive choice for my needs. Phone I bought was exactly as described. I paid £5 for next day and the phone arrived as promised. My first option for any tech when I need it. Thank you.

    I am delighted with my S 21 Ultra, when I ordered a phone that was fair condition with light signs of wear, I didn't think that I would receive an item in such brilliant condition. For all I new this could have been a brand new phone just not in its original box. I was also concerned about the battery condition but I'm delighted to say that it's also spot on. Bought a spigen case for it, which is just a quality case. Chuffed to bits

    was the first time coming across this online store, I was very sceptical as the prices were very low so I carefully read every review and edited to purchase the s21 ultra. It arrived less then 48 hours later with clear communication on tracking and delivery, opened the box and the phone was in prestige condition basically brand new will never be using a highstreet store for phones etc again this is definitely the new go to. I oped for the fair condition the cheapest one so didn't expect the service and item I received. thankyou back market

    So 1st phone I ordered took a while to come but it was ordered late on a Friday and it was a bank holiday wkend... When it came, on first glance it looked amazing for a fair condition phone, but then I realised the back was coming off and it looked to have an ott amount of adhesive inside it. I was gutted because other than that it was an amazing phone in excellent condition!! And, I was desperate for a phone!! . So then i have to send it back and wait for the refund before I could get another.. It was a total pain in the arse. So I'm knocking a star off purely because someone should have checked the phone better before they sent it! But due to how good the phone was (not counting the back hanging off), the prices, warranty, straightforward refund etc etc and most of all the tons of good reviews compared to bad ones., I decided I would give back market another go... And I am sooo glad I did.. Got an awesome phone for the price, got fair condition and it's like brand new!! Came the next day as well!! I'm well chuffed!! 😁😁😁 (would have been 5stars!!)
