It's just propaganda. It's useless. The purpose is to make more money. It's no use. I exaggerated its efficacy. I'm in this business. Many products are not as good as advertised. The more expensive things are, the less effective they are. Liar, don't buy TV. It's all these advertisements, fake mobile phones, fake laptops, medical advertisements, slimming products, cosmetics, health care products ... Modern people are more and more greedy, thinking about the good things that fall from the sky all day, and TV shopping cheats such people's money! ! ! Please be vigilant and don't be fooled.
