I guess it depends. If someone pays 30 bones on a bracelet hoping it helps and it does nothing or even worse, then sure, they're due for some ridicule. But if I told you that I could snap my fingers and you'd drop on average 4 strokes a round immediately, which may improve, and it'll cost you $30. Would you pay that? I'd say probably. I'd venture to guess you've probably spent a lot more on plastic than you should have, haven't we all on this site? My point is, I don't think you should write something off simply because it has a placebo effect, and that $30 for something that helps you focus, concentrate and gives you increased confidence isn't really all that insane, if in fact it does those things for you. If you pay it magically thinking it'll help and it does nothing, then yeah, that sucks.
