5/5Ordered 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.

5/5I 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.

5/5my device was just as described, however within a few days it was clear it had a fault with mobile data. I contacted back market via help section. I received an identical phone the next day, and once my new phone had been updated I returned the faulty one. I was amazed how easy the issue I had was felt with and sorted. excellent service and the phone is working as it should.
