Had some trouble signing up for software required Epson global account. Error messages were that I had wrong Email or password. I used two emails and the same message popped up. Epson support FQA was not helpful. Support phone number does not handle M-tracer. went thru 4 transfers to get section that could help. While waiting for techs computer to re-boot, it occurred to me that the system may not recognize local email services. I signed in with my gmail account and was successful. Advice" use a national accounts ie yahoo, gmail, msn. As far as the M-tracer, I like it so far. The pre-loaded Pro swing recorded is very helpful for comparison. I would like other Pro examples, even if had to download. Explanation of each of the variables are good but could use little more information. Like the "Golf Bag" function of getting computation variable more precise. I like the swing recording showing where the release points should be, very helpful. Especially since mine are weak and in wrong places. Another variable that I will find helpful is the attack angle of the ball strike. Look forward to further updates and adding more analytical information.
