I shoot with an NO-Peep and I am down to 7 target arrows. Next year I' ll need to get at least another dozen or two.

Knowing whether you shoot right or left handed then which eye is dominalt are important factors.

Although I shoot Right Handed and am Right Eye Dominant, when I forst started shooting with the No-Peep, the Left Eye always wanted to take over for my Right Eye [don' t ask why, I don' t know] causing me to miss the target on several occasions.

Being stubborn and Irish, I stuck with it and learned that when my Left Eye tried to take over all I needed to do was to squint my left eye down and it worked. My left Eye is no longer a problem and I don' t even have to pay attention to the No-Peep any more . . . It is just there . . . and centered as it is supposed to be and both eyes are naturally open.

I won' t go back is a terrific tool. However, you must know that at my first experiences I too was ready to throw it away but I stuck it out and I' m not sorry. I highly recommend it for its many benefits; one of which can bo an increase of 8-9 fps in speed and no string blocked peep holes at an inopportune moment.
