Well I'll say it, the thing didn't work for me...... hate to say your wasting your time with the no-peep but your wasteing your time with the no-peep. Everyone I know that has tried them has taken them off. and everyone of them is more accurate with a peep on the string. One of them is a professional shooter and he really doesn't like to use a peep either but he couldn't get the accuracy without the peep.
