I get free infrared light and plenty from the sun. With too much cloudy weather with additional infrared lamps. They work too, in my experience...and the proof is that it has grown into a $300 million dollar company.
,..they only have to have 5 people they refer order to pay for a patch. So the business aspect can make these patches free for distributors, but they have to help spread the word, which is what makes network marketing so powerful.
That worked for me, as also my remissions show. If not, I would build such simple infrared reflectors myself..
I would never participate in such pyramid scheme kind of marketing.
Even many middle class people wrongly think regular investments are ethically not problematic. But they sure mostly are, by transferring wealth from the poor - and exactly the middle class not scrupleless investing too, for a vast part to ever more and richer billionaires (see the exponential growth during the last 20 years only on the wikipedia site: Worlds Billionaires)
Avoid all huge corporations, don't participate in this manslaughter for easy money, by investing in, and buying from, ethically behaving small businesses only. Otherwise, you become the monster you thought to fight.
