Gets to the cause of neck stiffness & discomfort fast - Posture Pump 1000 Cervical Back Disc Traction Hydrator

Where can I get instructions for use?

Does the postual cervical disc hydrator work as well as an inversion table for the lumbar disc?

Does this model have a chin strip?

The heading says model 1000 and shows the chin strap. the product description says model 1100s kit 1. which is it? i don't want it if no chinstrap
