Quick! Whats the difference between these two items, both found on the Mets Online Shop and both officially licensed by Major League Baseball?
The first Item will get you two bracelets for about 20 bucks, the second will get you one for 27. What's the 17 dollar difference per bracelet for then? That is a question that even the makers of the second product actually cannot tell you. The second item pictured is a phiten bracelet, if you recall, Pedro Feliciano used to wear a phiten tornado around his neck. They are products that claim to use metals like titanium to jive with your bodies natural frequencies to give you better balance, etc.
Rubbish.
As a scientist, I can tell you there is nothing about that product that does anything like that with your body because…your body doesn't have “natural frequencies” like this product claims you have. When you see commercials for this product and similar products, there is a reason why they have to say you can send the product back for a full refund if it doesn't work. They need to say it because there is no science backing up their claims, and without that clause, they are selling snake oil.
The normal defense that somebody uses for these products are the commercials that show people magically getting their balance back with these products. To those people, behold this 10 minute youtube video explaining everything:
When a product makes a claim without evidence, be skeptical. As for the MLB, this isn't a surprise. It helps them make money. I'm not saying the product is completely worthless, I think it looks better than the other bracelet, but it doesn't actually do anything, and for that reason, it is way too expensive.
