This might be more useful than initially thought

Very much no frills, no shipping box, no case, no instructions, I suppose this is the kind of item that you should already be familiar with before ordering. 

They say it comes with a "charging cable", that almost insinuates that there is a battery and it's rechargeable... It's not, it does have a USB power cable, not for charging. 

I assume it works, you plug it up, it lights up, no sound, nothing to indicate it's doing anything. The Amazon listing just shows a bunch of pictures of this device in front of an oscilloscope, the images look like they might be Photoshopped or AI generated. The video appears to be legit, but again with no or little explanations, it's still a mystery. 

There appears to be an audio jack on the side, but with no documentation, I have no way of knowing what that's for.

I will be doing some deeper dives to learn more about this, I'm a bit familiar with Rife technology, someone in the Amazon reviews mentioned that, I'll be researching to see if I can use this to generate those frequencies. 

My biggest complaint is the lack of documentation and instructions. I know you can't make medical claims, but there are ways of wording things to give more clues as to how to use this and what it's potentially used for.
