Who sent it? That's a pretty noticeable flaw that should have been picked up by the TD BUT like live1 said I couldn't even tell in the first picture either so did your QC images show different angles of the bezel etc at all and was it something you noticed straight away with the naked eye?..
the point is NOT the visibility of the defect from the QC pics ... the seller KNOWS the defect, THIS IS ENOUGH SO THAT he does not sell that piece ...
moreover : my Sd had spring broken and bezel locked.. the QC do not shows this...
it's need the honesty from TD
