not saying its the best invention ever or it will save everyone from breaking their neck for the rest of their lives but you have to realize that companies that pioneer something have extensive testing/engineering time put into it. I hate to pay 500 bucks for something as much as the next guy, but I also don't expect engineers to do development for free.I understand the mechanics and for $500 they SHOULD have more words on their website. But if the donut will do an adequate job(enough people use them, that's for sure), then I'm good with $34.
Call this ignorant or whatever you will, but I'm nowhere near WC speeds or on equivelant courses, and YES, I understand I can break my neck stepping off a curb. But I'm not going to the store in a $500 brace either.
Basically, I, too, am annoyed with the cost. It shouldn't matter if "my neck is worth $500" because apparently it is to the manufacturer. My wife disagrees....
