I've been having one for a while now, and I never could achieve consistency shooting off the string. I initially bought the no peep to take my peep off and utilize all available light, but I just couldn't change my form from shooting with a peep. So I figured "what the he!!", and I bought a no-loose peep (not the rubber band type), drilled it out to at least 1/2" (very large - my friends thought I'd lost it!), and set the no-peep to my initial form shooting with a peep. It did take a while for me to get things set just right, but now I can see EVERYTHING through my peep, I have not lost my "comfortable" form, and can rip off feathers at 30 yds if I shoot at the same spot (I've learned not to do that now). Mine has never moved, and my bow has taken a few falls without incident. One thing is for sure though, when you set it - make sure you are comfortable. Eventually (after about 1000 shots), the no-peep trains you to draw the same way every time, so even if you can't see it, you are probbably right on the money. I shot in a dark tunnel for an indoor tournament where I couldn't see my no-peep the entire event (80 shots), and I won by 78 points! Made a believer out of me.
