Power Balance

My friend had one of these power balance wrist bands at school today. I put it on and did a test. (you can look on youtube to see these tests.) It was really cool. It actually helped with balance and flexibility…
Has anyone used this for pitching? It seems like all of the pitchers I see are wearing something around their necks. Is that what they are wearing?

A lot of pitchers wear Phiten necklaces.

I think they, like they wrist bands you are talking about, are gimmicks, but that’s just my opinion. If you think it helps you out, by all means rock it!
