Wonderful.

While it's not aesthetically sophisticated, it functions as a sciema with a display window, though only an LED is present. The general mid-power setting seems to be sufficient, providing current after muscle use. Its fit and functionality are confirmed, and it does work, although positive and negative effects haven't been observed yet. It appears to facilitate muscle work, but caution is advised regarding the intensity, as excessive power can cause neck pain the following day.
