A putting stroke you can't fake. The patented weighted-string shaft only swings cleanly when you make a true pendulum stroke. Let your hands take over, decelerate, or jab at the ball, and you feel it instantly.
Most golfers get the feel within 10–15 minutes. After that, a few minutes a day builds a rhythm you can trust.
