I am go glad that in your ultimate wisdom, that you can see this.
However, you need your eyes checked.
First, I have not posted this video as a result of personal humility. It has nothing to do with marketing as it would be far more effective as a marketing tool if it was posted. It is extremely convincing.
Second, I am not doing this to make money but actually to let people know that they are being deceived by the medical industry. The use of electricity as a cure has been around since the 1750's, actually even earlier. It has experienced nearly continuous suppression since then.
If many people had these, there would be a lot less concern and far fewer lives lost from the current Coronavirus Pandemic IMHO.
The problem is that while the Thiel study definitely shows better results for those who use zappers, it is very outdated and needs to be done again with the newer improved zappers.
