Seriously, if you want a bunch of feedback on the Dynatrac stuff you might try Pirate. Lotsa bling running around that site. That said, I don't recall ever heaing of a failure that wasn't caused by "external influinces".
I totally understand your concern. For ~$600 a set, they better be made of unobtanium, give free blowjobs twice a week, and last forever.
