"Model B!" What is it?

I have a Colon Hydrotherapy machine that is boiler plated as the "Toxigen Model B." It gives great colonic irrigations/therapy. Recently, while reading, on Zity "Enemas" I came upon the description of a Model B that seems to be something other than a colonic machine like mine.

Can anyone tell me what this Model B is and who is distributing it?

The model B talked about is a silicone rubber nozzle made by www.SiliconeNozzles.com .

The Model B that is usually referenced here is a nozzle made and sold by www.siliconenozzles.com.

You will find many comments in zity about user experiences with Model B, including preferences for durometer (firmness/softness). They're available in a rainbow of colors and are made to order, although there are sometimes "Ready to Ship" versions available under that heading on the website.
