I have the swingperfect pro too. I have to agree that this is for swingers and not hitters. I like it because it does tell me when I cross over at the top (which I can't see on the range) and you can hit balls with it. I do find that it does tend to buzz a bit at set up (don't know why) and won't if you get to the parallel toe up position on backswing. Then to top and if you are parallel to line it won't buzz (otherwise, buzz away). On follow through, slow speed, it won't buzz if parallel at waist high (toe up, horizonal hinging) but will using angled or vertical hinge actions.

All in all, very interesting toy. I did put it on my laser club to see how close it was to the "real" plane I practice in the house and it is suprisingly accurate. On at mid back, top, and mid follow through.

Don't know how it works but I use it just before practice and just after to work on my position at the top of my backswing. It has certainly helped me for that reason. I would probably recommend the regular over the pro because the tolerances are really, really tight on the pro and it took me a while to get it to not buzz which was a little frustrating.
