I have one. So far I've used for 3-D and target practice. I liked the idea of being able to ajust it at full draw. I've ajusted it at 3-D shoots and found it very easy to do. Looking foward to using it in a couple week when season opens.I tried it out in my blind last weekend in the late afternoon and the pin was very easy to see. We'll see how it workswith the blind in the woods.
