Lightspeed 3G Headset Updates?

Well Google shows the most recent solicitation from the group for feedback
on the Lightspeed 3G headsets was back in early 2003. Jay Honeck gave a very
positive update in March of 2004 in response to another post but no mass
(relatively speaking) feedback on general experiences. Soooooo....if I may:

1) What model and how long have you had them?

2) What was your longest trip and were they still comfortable at the end?

3) How many times have they broken (if any) and what broke?

4) Is the customer service and/or turnaround on repairs still good?

I think Jay's bought two new Twenty 3G's since March so I'd be interested to
see if they've proved as good as the first pair. Also, if anyone's gone FROM
a Lightspeed headset to another with good results, that would be interesting
too (well, to me at least).

Thanks!
