There are positives and some not so positive things about the no-peep. It has been mentioned about the training aspect concerning ones anchor point. It does eliminate the need for a peep. Legal low light conditions were never a problem. If the instructions are followed accuracy is not a problem. For a lot of guys it is just what the doctor ordered.
There are some things I don't like about the no-peep (keep in mind no product is perfect). There is no "accountablility" with the no-peep. By that I mean if you look through a peep you know you have to line up the peep and the pins or your shot is going to go awry. Not so with the no-peep. You can fire that bow without ever checking the rings and not think anything about it.
Of course there are a couple of rebuttles to that scenario.
1. A guy should practice so much with the no-peep that he doesn't have to look at the rings to make sure they are lined up. While I would agree for the most part, there are awkward positions one can be put into during hunting where you must check those rings to be sure of an accurate shot.
2. Checking those rings should be no different than making sure the peep is lined up on the pins; just another form of checking things down when the moment of truth arrives. Again in theory that is true. However FOR ME, using my peripheral vision during this critical period drains my concentration and my accuracy suffers. It isn't just the no-peep I have had the same results with a simple level on my sight.
Again these are just observations that I have made after using the product that pertain to my particular style (or handicap if you will

). For many it will be a great "find".
