I disagree. Don't base such statistics on usenet posts. They are in NO
way representative of what's really happening. Can't be, by design.

I take your point, and "Statistically Speaking" I wouldn't have a clue what
the "Margin of Error" is amongst usenet - however - If you have a bunch of
posts from Bose owners telling how their headsets are 99% reliable and
customer service is above question, and a bunch of posts from lightspeed
owners who (nearly) all say "Great customer service, just a pity I've needed
so much of it" then I stand by my assertation that it's a red flag.

Buying a unit from a company with a poor record for quality control doesn't
mean that everyone who does will get a dud - but it does increase the
chances dramatically. You're one of the 'trouble free' percentage, so well
done.
