Query: Instructional DVD is very helpful

I finally got around to viewing the DVD this morning. It's very helpful. I like to see the Thera Cane being used as opposed to just reading about it in the manual. It's not super slick, and they don't always cover using the tool on both sides of the body, but it's enough to know that the instructions are there, and I can pause the DVD to do the other side on my own if I feel the need to do so. My back and shoulders feel much better after my first session. The DVD is very reasonable priced, and well worth the $5.
