I got this for my Diamond The Rock bow, which had NO recoil and it was whisper quiet to start with. So i did not notice anything different in those categories. It looks cool on the bow so that's a plus. And also it does balance out the bow a bit, not that my rock needed balancing though. What i did notice is that it did seem to give me a much better grouping size in general. But i notices that with it attached, and i have no clue as to why this is, but the arrows fly out weird and you can notice them flailing about mid flight. They arrows still wind up hitting where i put them so i dont know. It just kinda makes me uncomfortable. Like the fly in a more circular motion then straight, so what ever. If that doesnt bother you. i guess this product is just ok.

Pros - looks really cool
tightened grouping size
balanced out the bow

Cons - did nothing for vibration and noise (but then again, nothing could be bettered on this bow, it comes with no noise and recoil, so i dont know how this stabilizer preforms on other bows in this category.)
makes the arrows fly out in a circular motion instead of straight, but arrows still hit the mark so idk here.
make me feel uncomfortable about arrow path, but doesnt affect accuracy in a negative way.

So i dont really know how to call this one other than just ok. i could of done with out it on my bow. But then again this is one of the best bows from a great manufacturer. So maybe it would be better on a lesser bow. 3 stars
