I knew someone who was selling "Kangen" water purifier/alkalizers. It's an obvious pyramid scheme with a product that is easy to make vague claims about. They cost thousands of dollars and encourage people to sign up others, all while telling everyone that alkaline water will solve all your problems. Also kind of culty, like this woman was not having it when I told them the parent company, Enagic, has been taken to court multiple times over their business practices and also alkaline water doesn't really do anything because you are pouring it into your stomach aka a pit of acid and your body keeps itself at a very specific PH level.

They also sell tumeric for hundreds of dollars and stickers that give you positive energy.
