Query: Does it really work?

OK. I regularly shoot in the 80s. 85, 83, 87, 86, 84, and an occasional 90. I've never shot lower than 82 EVER in my 10+ years of golf. I don't take lessons. I don't go to the range. I play just to play. So, I'd figure the only way I can break 80 is to take lessons. I won't do that.So last year, I bought one of these things and one of those necklaces. I sit in front of a computer for 9 hours a day and heard that these things might help. Well I noticed no 'pain relief' on the course. However, I shot a 79 last summer, with no changes in equipment, balls, stance, or even hats. The only difference is that I wore this and the necklace.Strange coincidence? Maybe...maybe not. It was a good buy for me.
