1, nice appearance. In design, the light shield semiconductor laser therapeutic instrument is similar to a watch, but it is larger and heavier, and can be recharged for several days at a time.
2, the effect is good. Functionally, I felt comfortable when I first put it on, but I didn't feel any obvious effect. But besides being worn on the wrist, there are many accessories with phototherapy head and external irradiation plate, which can really relieve the pain of rheumatoid arthritis.
