I have it on mine (CJ Dead Nuts 2 Comp). Don't have it set...somewhat know how to set it. From what I hear, there is a decent way and an even better way to set it. I'm familiar with hanging a string and weight off the ceiling, squatting down and drawing back and tilting upwards, lining the sight side of the riser parallel with the string and looking at the level. However, from what I've read on here from I believe TSOC, and Arthur_P, you should have a properly set 4th axis to get a true 3rd axis, and that 3rd axis is best done with a 3rd axis tool that is done OFF the bow (can be done on the bow as well). So I definitiely claim #1, and probably some of #2.
