Chris Mayson coaches players who have been number one in the world, and he says he rarely puts a training aid in a student's hands. Brian Henninger has won on Tour and he's tried just about every wrist trainer there is. They both use Wrist-X, for the same reason: it tells you the angle your wrist actually hit, in the moment you hit it. Set your threshold anywhere from 0 to 70 degrees, swing, listen. 99-day money-back guarantee.
