How about Dr. Li's products? I want a lumbar vertebra therapeutic apparatus.

I don't know what you are asking. The lumbar vertebra instrument you mentioned has never been used, only their cervical vertebra instrument has been used, and the comfort is still very good. I only used it in the experience store, and compared with several doctors who pressed the cervical vertebra, it was still better, and that cervical vertebra instrument would also give off heat. If you can accept this price, you can still choose him If you are satisfied with my answer, please adopt it.
