Good product.
I hope I never need to use this, but it's sturdy and well-designed if I do.  If you are going to carry this, be sure to practice with it, including one-handed and in the dark.  You never know what the situation will be if you do need it.  Also, be sure to throw a permanent marker (sharpie) in with your kit so that you can mark the time that you put this baby on someone if you use it.
