Putting is not complicated. The ball is resting on the green, you look at where it is in relation to the hole and hit it so the ball rolls in. Easy.
Sure. Tell that to someone who just three-jacked from 10 feet.
The EEZ-Read (pronounced easy read) is a simple device designed to help players develop a better sense of break and slope on greens. A simple level mounted on a stainless steel disk, it rests on the ground to show which way the green tilts. When the bubble floats toward the 12 o'clock position, the putt is uphill, 6 o'clock means downhill, 3 o'clock means it breaks from right to left and 9 o'cock means left to right.
By rule, you cannot use the EEZ-Read during play, but Momentus--maker of the EEZ-Read--says golfers who practice using the device will become better at reading greens and more confident when putting.
Is it worth paying $14.95 for a silver-dollar-sized disk with a level on it? Maybe. Even if it doesn't help your putting, you can probably use it to hang curtains.
