Targeted Relief: Devices often provide up to 12mm of oscillation amplitude, penetrating deep into muscle groups, such as the back, calves, and thighs.
Customizable Intensity: Most models feature 6-speed adjustments, with lower speeds (1-2) for relaxation and higher speeds (5-6) for deep tissue/professional, high-frequency, or high-amplitude massage.
Interchangeable Heads: Common attachments include a spherical head (large muscles), U-shaped head (spine/Achilles), cylindrical head (deep tissue/meridians), and flat head (general, full-body).
Battery Life: Rechargeable, with 1800mAh to 2500mAh batteries offering between 1.5 to 8 hours of use, depending on the intensity settings.
