Purchased a "pristine" iphone 7, but when received had some aspects which did not work. Arranged through online customer services to return it for a refund. Although they could not comment as to whether an alternative "pristine phone" would work properly, I purchased a second phone prior to sending the first one back. This was because they could not help by doing an immediate swap. This "pristine" iphone has just arrived four days late and seems also to have issues - the touch ID does not work, for example. So now I have 2 "pristine" iphones - both with issues which would have shown up had they been properly checked, to send back. Musicmagpie says that it performs extensive checks but this is clearly not correct. Really disappointed with my experience and cannot recommend.
