AP - your full quote as requested .....
"A shake down is meant to pick up on manufacturing problems/ quality and isn't meant to pick up design defects as this appears to be. If this was a manufacturing quality problem then at least call it as one and the issue should be dropped, if not it shoud be a concern! "
"design defects as this appears to be"
or
"manufacturing quality problem"
just so I have it clear in my mind, What design defect or quality problem are you referring too?
