I so far am very impressed with it. Being the jack is a screw kind VS a climbing jack, I can fine tune this going up or down in very small amounts. I was shooting the other day off it, and it was working better then the one I used to shoot off of at my friends. He paid $89.00 for his, and I like mine better. Of course mine is custom fitted to me, so that might have a lot to do with it.
