The movement of P-plate is not defective but normal. P-plate was designed to allow movement to flexibly rotate to fit the different facial contour of each person, and to properly react to the facial movement.

After it is properly seated in the face after wearing, it maintains constant fixation force continuously.

The movement of the P-plate is our work to effectively control the facial balance taking into account of the facial balance; in addition, each component of HEADrang was manufactured and rigorously tested to exhibit its performance.
