This device works as promised. The metal sphere encloses the head and makes the wearer feel very helpless. The best way to use this cage seems to be to place a leather hood onto the wearer followed by a leather or plastic collar. The globe can then be placed over the other restraints and locked into place. The inner leather hood and collar provide protection and padding for the head and neck. A cervical collar works well to stabilize the neck and prevents excess stress to the wearer. Great device. Very secure. Perfect for those who demand the utmost in security.
