Tim, can you give a little description on using it for sprains and bruises? My son's trainer is a well-known golf trainer and swears by the MP. He had my son use it for a sprained ankle to keep the blood flow going and reduce swelling. He also had him use it on a pretty bad bruise from blocking a ball that hit him square on a forearm bone.
There are so many uses for these things. Sometimes I'll have one connector hooked up to a sore body part while sitting on the couch and my wife will have the other connector on one of her sore muscles at the same time. Family bonding!
