This device applies Gua Sha, a Traditional Chinese Medicine therapy in which certain areas of the skin are repeatedly scraped. With the combination of vibration and warmth therapy, it relaxes tensed muscles and improves blood circulation. The design is inspired by the contours of the human body while the elongated handle provides an extension for hard-to-reach areas like the lower back. In terms of ergonomics, the device centralises the weight of the massage head for good massage feeling and it is comfortable to hold.
