I have had the opportunity to try the No-Peep in recent years and found that it did help to maintain consistant form and head position for the shot. Eventually you do not even look at it when you are about to shoot. They may still sell some of the "blemished" units via their website if you are interested. Either that or something like the hindsight would give you the highest level of light since neither restricts it in the way that a peep does.
