"In doing so, the mandibular advancement (extent by which the lower jaw is moved forward) can be calibrated from 0 – 10 mm (infinitely variable calibration)." No, you can't calibrate the position of your lower jaw. It's a one piece device, your lower jaw can only be aligned inline with your upper front teeth. Package, order and delivery process was good by the way.
