I am definately sold on it's simplicity. After putting one on my treestand bow and using it this season I am planning on picking another one up for my backup bow. I'm tired of trying to make my fletchings clear my rest. With the bisquit, it's gonna hit it- but equally.
I chronoed my primary bow before and after and could not see a significant loss of speed. My five arrow average was still the same 252fps I had before installation. I think my bow was actually tuned better afterwards because it is now "easier" to shoot.

When I'm getting set up in my climber in the morning I put my bow in it's holder upside down before removing the quiver(arrows would hit stand if right side up w/ quiver on), now I can do this with an arrow knocked on my upside down bow- too cool!!!
