i think a few people have sent several units back (probably wouldnt have happened if they waited for the fixes to be sorted out)
Except, how were some of us to even know, for example, that the nub company had made errors in the manufacture of the nubs, exactly?

Do you think I, for example, expected to have to send two units back? There's *no way* that one could have been avoided.
It's all well and good saying the above with the benefit of hindsight, but at the time the existence of the tolerance issue from this example wasn't even known.

EDIT: And even in that case, a month of waiting went by with the second return for the fully-tested nubs, as well.
