After running mine for a while, I really like it. What has worked best for me is to forget about using any kind of reference point, be it part of the optic, the sights, or anything else, but instead just do the same thing I would do in close range (sub 10 yards) instictive center mass point shooting. If I try to look for the dot like I would a front sight, I have a hard time occasionally, but if I just focus on my target and instinctively point the gun center mass like I was close, without thinking about it, the dot just appears in the window and I can take my shot, and it is faster than trying to shoot irons. The speed advantage increases substantially beyond 10 yards too
