I have one and I use it all the time. Like stated above, it works great on long sits. I use a turkey lounger a lot because of my back so it is very useful. Even when I'm on the move it is with me. The strap it comes with keeps it in reach when needed and out of the way when not. The rest itself is firm and swivels and it stays in place on the knee. It definitely allows you to rest your arms when working a box or pot while at the same time keeping your gun in the ready position. In my opinion, it is way better than the Hunter Specialties rest.
