I know a gentleman who has two. Our take on them is that they are an interesting collector piece, but have very little practical value. After seeing how powerful they are, driving the blade to the hilt in 3/4 inch plywood at 15 feet, and how sensitive the trigger mechanism is, we agreed it is as dangerous to the user as the BG. The idea of carrying one concealed on my person, even with the safety on, is scary.
