Although I like the Medicus, I'll begin by saying it does NOT replace private instruction from a pro.I whole heartedly agree. I have had several lessons and have benifited greatly from them. I have a basic understanding of my swings mechanics and am hoping to reinforce the good habits I have learned thru practice and the lessons. My goal is to maximize my time practicing because that time is shorter than ever now.It sounds like it has worked as a good "reminder" for those who have used it because they seem to pull it out when things aren't going just right and it gets them back on track. I think I will have to do some hands on testing for my self. It does look like what I am looking for. I'll keep you updated. Thanks for the help!
