The instructo-swing teaching aid does not represent the swing mechanics of Ken Griffey. It is a true shame that he indorsed such a product. The plane of his swing is on a slightly upward plane, not downward as this mechanism requires. Further, Griffey uses a good rotational swing, but this mechanism requires a hitter to use weight shift and extension mechanics (or the nob will pop-out before contact). Many people will recommend this product because it represents the old, out-of-date mechanics that many coaches still preach (goes right along with quick hands, keep the shoulder in there types of instruction).

Do not allow your "daughter" to use this "teaching aid" from Griffey in combination with Jack's rotational and torque mechanics, they cannot work together. In addition, becoming a great hitter and this teaching aid will also not work in conjunction. Griffey, McGwire, Sosa and all great hitter use rotation and torque, but the minute rotation and torque are applied to this aid, the end nob will pop out indicating a "flawed swing," which is 100% incorrect.

In my opinion, Jack would have a large DISCLAIMER warning not to use this product along with the mechanics of rotation and torque that great hitters use. Lastly, Jack I am excitedly awaiting the video to learn exactly how to use the mechanics that you teach.
