Not Necessary
The CD arrived a week or so after the Sinucleanse neti pot and saline packets I'd ordered. So, before it arrived, I found a demo video online for another brand of neti pot and I learned how to use one correctly. When the CD came, I looked at it to see if I'd missed anything important. The CD did include background information about the location of the sinuses and how the sinus rinse worked on them, in addition to a demo of the neti pot use. The CD was informational and interesting, but not necessary. Save your money and watch a demo video at no-cost online; plus you won't have to wait for the item to be shipped.
