Check Wrist / Low-frequency massager

When people ride a bike for a long time, they overstrain their wrists, and carpal tunnel syndrome occurs frequently. This low-frequency massager is a good remedy for carpal tunnel syndrome. However, it is very inconvenient to massage your wrist with a regular low-frequency massager. So I designed a new low-frequency massager. Check Wrist is a new type of low-frequency massage device to cure it. According to the way the user wears it, it can massage in narrow or broad dimension. Ordinary user can wear it as bracelet, also getting bio information through mobile app.
