Hey Truborshooter !!
I have been using the banners for about a year now and I have to say, I think they do work. My times have dropped significantly and by no means, I'm not as fast as KC or MAX etc... Primarily i shoot limited and in last month match I was 4th overall and first place in limited. Scores are in practiscore. ( Hansen Steel ) Punta Gorda Florida. There's another match this Saturday and right now I have Five to go set up in my living room. I have all 8 stages by the way. In my opinion, they do help with your dryfire routines.
