I sent a pretty much perfect Samsung S7 after they offered me £125 online. They then sent an email saying the phone had screen burn mostly visible on white background and reduced it to £35. Not a chance anything was wrong with the phone and not a chance I was accepting this offer. It was in such good condition I wasn't going to bother upgrading so there is no way there was screen burn. They are con artists pure and simple and prey on the fact most people can't be bothered to get it back to do the whole process again. I would rather leave it in a cupboard than let these scam artists make profit on a mint condition handset. AVOID!
