As a physical therapist specializing in pelvic floor dysfunction I feel there are a lot of great features your dilators offer for my patients. It is nice to see a product that is manufactured in the USA. The brochure itself is an excellent resource, with all the reference articles listed.
Also I think it is extremely beneficial for patients to see (as you have listed) how the silicone dilators relate to “real life experiences”, i.e. tampon use. For many this will help them to see a goal in mind while they are working. The ability to chill or warm the silicone is also a huge benefit. Furthermore, I feel that your #1 size will be especially helpful for many women.
