FANTASTIC!!!!!!!!!!!!!
I've been having sacro problems for about a year now.  I'm an avid golfer and golf irritates the problem.  When it hurts it's hard to golf.  Got this thing last week, used it for 15 minutes that night and played my first pain free round in months.  No pills for me!!!  Played 5 round since and same result. No pain.  Buy this product if you have my problem.
