not a good quality
found it very low quality item after use. there is no vibration in touch points, its only vibrating in centre and there is no significant pulse to where it touches the scalp. it does not have connection to the points of touch. just waste of money. the manufacturing is also low quality and difficult to adjust to head. its grip is also very uncomfortable. overall a useless product. and it not possible to return at Ali Express because they ask return goods at your cost, from overseas.
