Just back yard target shooting with mine. I made a modified bracket for it and used it for a while. I couldn't keep tight groups with it. I then resorted to using it in combination with a peep and found that the slightest torquing showed clearly with it. It gave a 3-point sight alignment and I had really tight groups. Other than that, it just doesn't seem to work for me. Maybe the sighting gap was too big, like a peep that has too large a diameter. I bought a Trophy Ridge Flatliner and the way the pins line up flat, you get the same visual cue on torquing as with the Hind Sight. Used in combination with a C-Peep and I get good low-light shooting abilities. If you have really good form and don't mind the pain in the butt it is to set it up, give it a try. Get a rubber washer to isolate the bracket from other parts as it will vibrate some on the shot.
Hope this helps a little
