I can't thank you enough for producing the Straight Arm! Before your Straight Arm there were some pretty flimsy products trying to keep golfers' arms straight during the golf swing. As a former PGA New England Teacher Of The Year, and having given over fifty thousand golf lessons, I have been using the men's and ladies/junior Straight Arms every day for over ten years! I strongly recommend the Straight Arm to any students, and I use it on every beginning student that comes to me for their very first lesson.
