How to identify carbon fiber yuba (commonly known as warm therapy)?

The radiation effect of carbon fiber Yuba is extremely poor. In fact, the principle is the same as the traditional quartz tube heater. The radiation distance is only about 60CM. When you hold it in front of your heel, you can feel its heat. A little further, it doesn't matter at all. The thermal radiation is concentrated within 20CM, and the radiation distance and heating effect of Yuba are much greater than that of carbon fiber Yuba, which is why large Yuba manufacturers do not produce carbon fiber Yuba heated by radiation. After all, the carbon fiber yuba for radiant heating is still immature. It's just that some unscrupulous manufacturers use consumers' ignorance of products to package some so-called concepts to mislead consumers. In fact, as long as they feel the heating effect of carbon fiber yuba at a normal bathing distance, their lies will not be debunked. Moreover, the chassis temperature of carbon fiber Yuba is too high and its safety performance is very poor.
