Pros: Construction, Materials, None
I HAVE CARRIED ONE OF THESE IN MY BACK POCKET,VEHICLE AND IN UNIFORM THROUGH THE YEARS. It is infallible like the standard slam- to- the- ground- to- close batons and has a commanding snap to deter the bad guys when deployed. Other batons have failed in less than a year, the autolock has been with me for years. I am getting another for practical use of my skills at stick fighting as another means of defense!
