I'm very sensitive to ems (electro muscle stimulation) and usually find it painful. If you're looking for a massaging, heating (only with red led light therapy) metal gua sha with vibration (sonic) massage, this is good.
The tiny microcurrents of the device feels really good on the face. Mimic wrinkles looks and feels more relaxed.
