The Black #3 110-150 lbs Unisex Golf Training Aid Trainer

Seeing pros like Harrington use it makes me want to avoid criticizing it but it didn't work for me. My right elbow needs to separate more in the backswing and the swing shirt would not allow that. I want to avoid the "flying right elbow" but can't restrict my right elbow from moving back and off my torso. This swing aid may work very well if you are already used to keeping your elbows close together.

This did nothing but screw up my golf swing
