Has anyone tried one of these ionic bracelets? My neighbor says they really work. Any opinions?

Hi,
Any type of bracelet is in the mind of the wearer. If you think it will work, then it will sometimes.
There are no statistics available concerning any types of bracelets being worn for anything, that actually work.
My wife tried some magnet bracelets, for pain, and they didn't work. Even the ionic bracelets are not proven; one way or another.
I do wish you the best, and good luck.
