Obviously this isn't a unique product - this sort of thing pops up all over the place. None the less, it's definitely worth a complaint. My brother was brief and vicious:
I wasted even more time with my complaint, which I directed straight to head office;
To the manager
I am concerned to learn that your store is selling the product "Power Balance Wristbands." My brother has submitted feedback on this; I would like to complain slightly more directly.
The product is clearly a sham. A clear effort is made in the product description to make it sound scientific; scientific buzzwords such as "resonate, electro-chemical exchange, energy field, frequency, energy flow, biological energy system, ionic balance, energy pathways" and so on. However, the explanation is completely empty; the words simply make it sound impressive (it always sounds impressive when people talk about energy fields. On closer inspection, for example, if you search Wikipedia for "energy fields," (I am a physics student; I have never studied or heard any physicist talk about energy fields) you get to a page talking about spiritual and alternative medicine, not a technical science page that you might expect. This clearly reveals, then, that the effort the writer of the description goes to to make the wristbands sound scientific is misleading, because this product is not based on any of the sciences it wantonly abuses - physics, chemistry, biology - but is an "alternative medicine."
Although the scientific principles the product description scratches the surface of are clearly totally mis-used, this does not fully address what the most important question clearly is: does it work? The description claims, firstly, that the product causes "improved balance, increased core strength, greater flexibility, increased range of motion and overall well-being." This claim receives no support - it's not even a "studies have shown the product creates improved balance..."
So, there is no science behind the product, and the best evidence that it works is a link to an article in a surfing magazine, which turns out to be an interview with a company representative - not an "independent review" as your page claims (please change that. it is false and deceptive). The sad truth is, thousands of products like this turn up, and they do get tested, and not a single one has been shown to work. The only effect they have is the placebo effect - people are influenced by their belief that they work. I'm not sure how much the wristbands cost, but unless they are exceptionally cheap they are too expensive for a placebo.
Products such as this should not be sold. They are useless and deceptive, and are bought by the gullible and the credulous. I suspect that the only crime your store's management is guilty of with regards to this product is the same gullibility and ignorance - but to sell this product in the knowledge that it does nothing would be deeply unethical, and I urge you to remove it from your shelves and demand a refund from your suppliers.
With regards, Jack Cowie
So I'm looking forward to receiving a reply full of corporate-speak.
