Q: I think the video was really good, im a nurse so i know most of the information already but it will hopefully help my husband. I think my husband preferred the video to an actual class. I mainly chose to use a video because of my schedule. The only thing I would have liked to see a little more was ways to help deal with the pain- like more breathing techniques. Overall I think it was good and would reccomend it.

A: Positive
