Sent my IPhone 12 to be sold with them, as they offered more than the shops in my town, graded 'good' as the only issue was 4 small scratches on the front and a battery health of 79%. First of all, your tracked delivery is only tracked to their local depot, NOT their address which is not clear.
I had an offer for £69 due to heavy cosmetic wear, which I was baffled at, and so I requested the phone to be returned to me. I received the phone and noticed quite a lot of scratches on my screen that wasn't there prior. I took this to the phone shops again and each one has now said my phone is worth about £85 when they originally all quoted me £150-£170. Thankfully a couple of the guys remembered me and I explained the situation and they had said that this has happened to a few other people, they come in for a quote, music magpie beat them toon a quote and they then grade it Lower when they get the phone. When it's returned it's damaged. Thankfully my phone turns on but the scratches are so visible and have now left my phone pretty much worthless. I have asked for compensation otherwise I will be taking this further. Do NOT use them.
