I have use the No-Peep and use conventional peeps on my target bows. I bought a Cougar4 SE with 32-3/4" A2A and am using a 30" draw. I was going to use the No-Peep, but decided to use the Anchor Sight.
It is great, even better than the No-Peep. I also use a Kisser button. I found both the Kisser was necessary with both. I could vary my anchor and vary my grip some and these devices will give me a false read. However, I am extremely accurate with these, even more that just the Kisser. For hunting it is the cat's meow (pune intended). It give me the ability to draw setup and find the target much faster than a normal peep and especially in low light conditions.
With this combination I can anchor the bow, look at the Anchor Sight and center IF necessary and then aim. It doesn't take too long to setup and has some very nice adjustments over the No-Peep. It will definitely be on all of my hunting bows.
