The electric moxibustion instrument is basically useless. Smoke and fire are called moxibustion, but Yagi fire cannot be moxibustion. The magical smokeless moxibustion and smokeless moxa sticks on the market can't be called moxibustion. The Aijiang smokeless moxibustion instrument you mentioned is a smokeless moxibustion instrument, but it can filter out excess smoke through water to make it smokeless.
