But never underestimate the scientific illiteracy (or the skepticism) of the American public! These things are selling like hotcakes. And the people who wear them absolutely refuse to believe anything other than the iRenew's claims.
There is no point trying to discuss it with them. Believe me, I've tried. People either believe in magnets and magic rubber bracelets or they do not, and never the twain shall meet.
One of the iRenew's claims is that it helps your balance. Leaving aside the issue of how this is even possible (hint: it isn't) the ad's claims are supported strictly by two-shots of people having their arm yanked on by some dude. In the first shot, they aren't wearing the bracelet, and the dude yanking their arm pulls them off balance. In the second shot, they are wearing the bracelet, and the dude yanking their arm does not pull them off balance.
This "actual demonstration" is about as real - and as realistic - as a Scrubbing Bubbles commercial. I mean, for one thing, you can easily see that in the first demonstration the dude is both yanking down and pulling them backwards. In the second demonstration, the dude only yanks down.
The only thing this demonstration proves is that iRenew's makers lack any shred of human decency. They are cunning personified, and they will say and do anything in order to get your twenty bucks.
(And that a lot of athletes, celebrities, and supposedly-random people at the mall are idiots.)
The ad repeatedly refers to the bracelet's "technology." Trust me, the only technology being used here is the sweatshop labor of the hundreds of Bangladeshi kids who are no doubt going blind assembling these rubber bands by the cartload.
According to the manufacturer, the iRenew bracelet helps to realign your biofield. This kind of talk reminds me of an anecdote I heard about Star Trek: Next Generation writers. When writing a script they would just have Data say "We need to tech the tech so that the techy tech is teched."
Later on, some consultant would come along and replace all the "tech" words with Star Trek technobabble terms like "Jeffries Tubes" and "resonant frequency."
Let me be clear: there is no such thing as a biofield. Certainly not one which affects your balance, strength, or endurance. Further to that, wearing a $20 rubber band around your wrist won't affect it. It's twenty bucks wasted. Isn't there something better you could be doing with that twenty bucks? I'm sure there is!
I'm usually bemused by infomercials. I figure, hey, it's your money, spend it how you want. Buyer beware, right? But in the case of the iRenew bracelet and its ilk, I firmly believe that everyone involved with this thing should be ashamed of themselves. If not in jail.
