A few minutes on the practice green with this mirror is all it takes. It locks in your eye position over the ball while training a straight-back, straight-through pendulum stroke - two of the most common putting flaws, fixed at once.
The Perfect Practice Putting Mirror shows you exactly where your eyes are relative to the ball and putter face, so there's no guessing and no bad habits going unchecked. A built-in ball slot and alignment lines give you an instant read on whether your setup is truly square.
Add it to your routine and watch the strokes disappear.
