AVOID AT ALL COSTS! I was offered £65 for my Samsung S7 which was in great condition. When Mazuma received it they revised my price down to £5 as they said there was Level 2 screen burn and a new screen was required - totally untrue! I rejected their 'kind' offer. The following day I received a text saying they had reassessed my phone which now had a red glow within the LCD (also incorrect) and they could now offer me £20. I also rejected this offer. It then took 2 weeks and 3 phone calls to them before I finally received my phone back - in a different box. I then sold my phone to O2 Recycle who offered me £56 and paid exactly that the same day they received it, proving to me that there were NO faults with my phone.
