Is Yifa Gold Health Vacuum Pot True or False?

It should be fake. The price of the product is 698, but the price on Alibaba is 50 yuan, and some are even lower. There was an activity in Jinan Eleventh that said to send something, and finally I cheated you into buying a pot for 200 yuan. After buying it, I found that the QR code on the product has not been verified, and the customer service phone can't get through. I can't find the corresponding product when I enter the developer's website. What is exasperating is that the people who engaged in the activities took the money and ran away without paying it back. Don't be deceived
