Anyone done the X-Rite Color Course? Worth it for Designers?

Has anyone attended the X-Rite Fundamentals of Color and Appearance seminar?
If so, was it worth it for you if you are an industrial designer? Or if not a designer what was your experience with it?

My company may be sending me to one, but first would like to gauge how useful it actually is to industrial designers.
