I have use one for 5 years now, could not imagine going back to a peep sight. That being said, just like anything else new it took some getting used to. I use vertical pins. The sight picture would seem to be crowded other wise. I purchased the x style, didn't like that. Again sight picture to crowded. So I nipped off the top of the x, much better. /\ like this. Sighting in is a little different, but they give good instructions. End result, great not looking through a peep,helpful with a consistent anchor. Worked for me, good luck!
