At present, the gyms in the market mainly use imported products. Mainly in Korea and Japan, the price is about tens of thousands to hundreds of thousands. At present, some domestic manufacturers have the ability to produce this product, and its performance is no different from that of foreign manufacturers. However, at present, no products in China have obtained medical registration license (which requires a lot of money), so they cannot be sold as medical products. Can only be sold to some beauty agencies.
The price of this product is tens of thousands even if it is made in China. For your own use, I recommend you to search for "body fat scale" on Taobao. This price is much cheaper and more suitable for home use.
