Below you will find links and videos highlighting the current manufacturers of several different styles of this innovative gear. Not all of the gear videos are the most current, as some of the designs are protected under non-disclosure agreements with the author or patents pending. As newer videos become available, this page will be updated. I have also included links to contact the manufacturers directly under each video.
The systems are presented in alphabetical order. Feel free to contact the author for any questions.
