They are in a class of things that you hope you never need. Life insurance, PLB’s, defensive firearms, pepper spray and Kevlar fit that bill. They are invaluable if you do. If you never need it you are happy. Most police departments in the US list them as mandatory. A hospital can usually save you if you are not shot in the head, neck or torso.

In extreme weather like golf ball sized hail, a Kevlar helmet and a military vest allowed me to get the stock in.

I have put mine on twice for other reasons. No shots were fired. I am still happy I had it on.

I have sold many of these over the years.
