The lyrics for the song used to help advertise the children's toy the Slinky included the line that "for fun it's the best of toys."
If the Swinkey - dubbed "The Golfer's Toolbox" - were the product being marketed by a song, the line would read "for golf it's the best of tools" or something, and except for the fact that many would be unable to get the damn song out of their heads, it wouldn't be far from the truth.
Training aids in golf are expensive. That's because if you're in the market for a golf training aid, you're more than likely able to afford an expensive one. At $99, the Swinkey is an expensive training aid if you view it as "a stick." But the Swinkey is more than a stick, and this review may convince you that $99 is a reasonable price.
