RE: Do NOT risk your life NEEDLESSLY...
I set it up yesterday in a tree in my buddies back yard. Including tying the prussic knot it took me about 5 min to set up. I jumped out of my tree stand about 5 ft off the ground and needless to say it wasn't very pleasant but it worked. At least I know what to look forward to if I fall.
I did learn one thing about the prussic knot is that if the guideline isn't tight and the prussic knot isn't tight then the knot may fail to grab. So keep everything snug.
