I agree with Straightarrow.
It is a great training device and you will see if there is any torque.
It is not the easiest thing to put on and set up but once it is on then it is not going anywhere.
For the first couple of weeks after you have it on you will be going back and forth between the no-peep and your pins checking to see if everything is ok.
But once you get your muscles trained for your grip and anchor point you will hardly look at it.
I have mine set above my sight and I can clearly see it in my periferal vision so I dont take my eyes off the target.
It is also great in low light situations I can still see the no-peep after there is not enough light to see the pin.
