I like the extremes and am thinking of getting one. It's only draw back that I can see is a small site window. However being small it should fit nicely inside of a peep. I have a CP 111 and it's alright. It's not the most expensive out there so I cut it some slack. It's draw backs are the level is not adjustable so if it's off (mine is) you have to improvise. The second and biggest is the 5 pins don't stack straigt up and down giving you shots that vary left and right at different distances. They also use steel screws (rust, not pretty). The Spot Hogg, I had a run in with the president and he turned me off to the company as a whole. There really is none that strike me.
