I shot most of the evening tonight with this rest and so far so good. I like how quiet it is. A far cry from my Trophy Taker in that regard. One thing I did notice. I did a quick group tune with it to get everything lined up out to about 40 yards or so. Since the rest does mount farther back than a normal drop away or prong rest, torque seems much more critical with it. I did have more left to right impacts with it than I'm used to.
I think I'll keep it for a while.

Its almost as ugly as the Zero Effect and weighs as much as the bow, but all in all, its seems pretty nifty.
