Selling medical devices is not a pyramid scheme, but a serious job. Divided into direct sales and distribution.
Usually, manufacturers can take the situation that dealers sell products everywhere, and some manufacturers use their own direct sales methods to sell products.
In layman's terms, it is the same as mobile phone manufacturers selling mobile phones.
The business model and nature of pyramid selling are different from that of medical device sales. Don't confuse them.
Product sales are based on product transactions to users and profit from the operating price difference.
MLM is based on products, and its main purpose is to attract people to pay. Finally, the purpose is to exploit the money paid offline for profit.
