I installed the No Peep on my bow last weekend and was able to remove my peep site completely. I' ve only used it for a few days and it takes some getting used to but it removes a lot of complexity added to your setup by using a peep site. My groups are actually better with the No Peep than with a peep. It occured to me, once I had removed the peep, that I always had to adjust my shooting a little bit to find my pins through the peep site. The No Peep is based on the concept of ensuring that you anchor consistently every time. What ends up happening is that you look at the No Peep for the first several shots and then you just know what feels right and you don' t really rely on it that much. Just my 2 cents worth...
