I am writing this in a neutral, scientific tone and no offense is meant It isn't a matter of liking or not liking, the point is "do they work"? Mathematically they work. They are proven to work. For me, I have tried both ways and seen many people shoot better with them including myself. If I had not experience in this, I would sit back and eat my popcorn. OP, yes they work and you should try shooting at 600+ with and without one to see if you like it. Buy a $5 Chinese ebay one, a $20 one or a $100 one that does your dishes. Up to you, but you should try one. If you hunt LR, then up in the mountains it is a must in my opinion because trees, brush, etc are not always perfectly plumb. Type in "scope level shooting" in youtube and watch a few videos also.
