I am starting to wonder about it a bit. I was always under the impression that it did do everything as advertised but after Len made a few comments about it awhile back I started tinkering with it a bit more. I believe it falls very much along the same lines as limbsavers in a sense. On some bows with certain setups it makes quite a difference in noise, recoil and vibration. While on other bows the change is negligible if at all noticeable.

Just some food for thought.
