Independent Shotmake Reviews
The Shotmaker golf shaft insert was recently named by a respected golf review site, MyGolfSpy, as the most impressive invention in the last 5 years. This is the highest honor MyGolfSpy has ever bestowed on any product.
In MyGolfSpy's independent tests, the Shotmaker produced an impressive 45% improvement in accuracy, 38% reduction in side spin along with lowered back spin and longer distance.
Since then, many respected equipment reviewers have published their own reviews. Below are links to some of them.
