hard to use [SEP] all parts and pieces were included and i recd day after ordering this is harder to use than i expected after watching a zillion youtube videos and already using the cloth headband method it is not something one should expect to master after only one or two triesi am wondering what is up with star reviews that when clicked says no such reviews to show currently using a cloth headband is working great for me but i am not ready to give up trying to use this just yet
