A friend of mine has one and he won't hunt out of anything else. He lost one of his cranks and had to buy another one. Make sure and locktite those on good.

I used it once and liked the leveling idea, but I like my sling type seat on my API better. I also don't like a bar in front of me. I could see a bottom limb or cam hitting that bar on a close in shot. And it is a good bit heavier than my API too, and pricier$$$.
