Just got mine today (thanks, Joe!) and it's everything they claim it to be.
I do have to wear my pants a waist size larger to do all the shifting they show in the video, but the fucker is extremely concealable even without going 'deep cover'. If you don't like a barrel pointing towards your nuts, you can wear it on your side or middle of your back.
I can bend, sit and squat with no problem with my Colt Officer's Model, and I don't have to worry about the damned thing popping out when I bend over to pick something up off the floor.
