I think a quick search with the word "Guardian" would be pretty helpful...

The general consensus is that it's one of the quietest, most shock-free and vibration-free shooting experiences you'll ever have. Some have complained a little about the stiffer draw cycle, which falls somewhere in between the smooth and the fast mods. So far, that's about the only perceived negative I've heard.

Most people rave and rave aboutthe lackof recoil and noise. Some have even saidthey can hear their release "click" upon the shot. Bill Winke's exact quote when discussing noise in one of his reviews was: "Noise? What noise?"

Technically speaking, the bow is the most efficient ever developed, transferring more energy into "push" than any other model before it. I love the way the limbs are bent at such a gentle arc, minimizing stress and doing away with the "diving-board effect" that occurs on all other bows. It's a graceful-looking design when looked at from a side profile where the limbs are concerned.

Hope that helps a bit. I think this bow -- more than any other one out there -- is just one of those that's gonna have to be shot to let you understand and appreciate all the advances designed into it.
