Its just a basic delta wave, without the right electro-magnetic waveform parameters to assure a reliable biological effect. If they do not tell you exactly what they are doing (if they did you would not need to ask me), it is probably because it is super simplistic, or they do not even know what they are doing. The secret of PEMF is that there really are no hidden secrets of PEMF; no magical frequencies or secret waveforms. Many PEMF products in the last 5 to 7 years use the waveform I developed because I make it very clear what it is and they just copy it because it works. So, they may have taken a crack of copying what I am doing, but I think it more likely they just are using a simple pulse generator (which might work, sometimes, a little bit).
A 30-day money back guarantee is just a way to get products into people’s hands. Even when they do not work, ~ 30% of people think they do (placebo), about a third will not even get around to seriously trying them within the 30-day period, and thus they feel “stuck” with it (their fault), many just lose interest and forget to return it, and many feel like they just need to try it more and “maybe it works(?)”, so since the money is already spent, they just keep it. Even if you sold an inert block of plastic, you would only get a certain % of them returned within 30 days. And very often, the return process is not as simple as advertised at the time of sale.
Even I am bad about this as a consumer: if I buy something that is a piece of junk, I usually just put it somewhere and chalk it up to the “tuition of life”, and hope to be smarter next time.
As for the device performance: I used to measure and characterize PEMF devices on the market. But usually they are so poorly designed, built, and calibrated, that their performance will change quite a bit from lot-to-lot. Some companies have no Idea what they are selling, an therefore have no way to exert quality control. I know this, because several have actually contacted me and asked me to calibrate and characterize their PEMF product because they do not know how to themselves.
Influencer: I have given two interviews to this particular influencer, one was done back-to-back with Bill Pawluk. We had a great expert back-to-back with lots of useful information. But Bill and I ended up getting cancelled out by his interview with a guy who was a used car salesman who recently “got into the PEMF business”. He had a great toothy smile and the Dunning-Kruger self confidence of an uneducated 20-something who had spent a weekend Googling something to become an “expert”. But he said all the things the influencer wanted him to say to really sell-sell-sell, with no depth of content more than statements such as “our PEMF can fix that!!” or “it will make you (stronger, smarter, faster).” I think the influencer eventually did get around to posting some of what Bill had to say, but it was clearly second-priority to the used car salesman guy.
He was not interested in our product because we would not make statements that it drives your athletic performance up to 110%!!, and nonsense like that. He gave me the impression that we really would not appeal to the demographic of his listeners. He seems to be happy to use our technology for his own injuries (he assures me that he would not travel without one), but not to promote it, because we also did not offer a huge affiliate fee for each sale attributed to his interview. Overall my impression of him was not positive, but a lot of people like him, so I could be wrong.
