They work but...
These balls work; they do exactly as advertised. I you put the club head on the ball and the ball is lined up as instructed on the tee they fly straight no matter your swing plane or how the clubhead strikes the ball. While I have not played them myself I have seen one of the worst "hookers" in golf with a horrendous stance and swing hit these straight down the middle. The two downsides to this are when hitting into a great you are instructed (by the manufacturer) to ensure proper alignment to get the best action. Of course that is illegal but for those of you that play it up I guess it doesn't matter. Next and probably more to the point these balls are illegal as stated by the USGA. They cannot be used for handicap scores, USGA sanctioned tournaments, etc. I am a bit surprised I haven't found this disclaimer in the advertising; or maybe I am not so surprised.
