I have also struggled with this training aid and also Greg Norman's secret, which I think both aim to achieve the same thing.

I have watched the Leadbetter instruction video for this but can't recall if HE hit any full shots with it on. I certainly think he hit chips with it on.

I think it would be useful for members like myself who struggle with training aids such as the answer and the secret, if a fellow member who does have success could put a video of them on the site with the aid in action. If this cannot be done, then a close up picture of someone with the device on at set up would help.
