This is the description from the website:
"Ever make a beautiful 10-foot putt on a level green only to notice the ball curve away from the hole at the last second? If you thought there must be something wrong with your equipment-you were more correct than you knew. Believe it or not, a perfectly round golf ball has never been manufactured!
Just like automobile tires appear to be perfectly round - yet they still need to be spin and balanced before being drive at high speeds. The same holds true for golf balls. The inherent lopsidedness of ever ball works against you off the tee and on the green.
The Check-Go automatically realigns the balls heaviest areas along its equator, so that the ball no longer has a tendency to wobble, but rather roll more accurately on the green and drive further off the tee with fewer hooks and slices.
The pros take advantage of every technological advance available to them - now you can do the same! Simply mark each ball's unique sweet spot before you play. You will enjoy more accurate shots, greater distance and lower scores."
