I agree there are easier cheaper ways to gain quick at the draw reactions.

Besides the one unspoken major thing that Youngblood hasnt mentioned is the unseen punch (the set up punch and the finisher) and the art required behind the moves in boxing to be able to deliver one. At the other end of the scale; reacting correctly to the opponents gravity ,balance and body movements when one is coming at you, to lessen the impact and to get you into the safest position to continue the fight; A machine cant help with that stuff and it must be determined whether it may eventually breed a habit that may work against that too.

Im not knocking it out of contentiont here, Im just saying every invention gets slapped in between the scales of justice, you have to take the knocks as well as the slaps on the back and adjust and learn from each.
