Firstly welcome to the board.
I have the No-Peep and love it.
It is a great eye alignment device it will let you know if there is any torque in the bow,it will teach you a consistant anchor point each and every time.
Now it is not the easiest thing to set up if you have some one to help you it is not so bad.
It took me 30 minutes to get it set right but once you have it right it dont move.
When you first put it on you will be looking at it back to the pins but that will only last a week or so.
I have mine above the sight behind the riser but you can have it below and in front of the riser what ever you want to put it.
Hope this helps.
