Kang Yi Jian's warmth physical therapy device effect is good?

I feel not as good as Xilaijian, although it is from the head roll to the feet, but the feeling of the human body structure does not quite fit, don't twist, it is quite a lot of fancy, but also with the medicine, and moxibustion, but people Xilaijian on a machine, the effect is better than it. Some people have to compare for a long time, for example, you do Xilaijian three months, and then do Kang Yijian three months to try which one is better.
