Got mine Saturday and was able to give it a few swings in the basement yesterday. I feel the weight is just right and am looking forward to taking it out to the range once it stops raining here. I can already tell that I like this more than my swing sock for warming up.
I found that my tempo was pretty close to the 3:1 ratio and it was not diffucult to adjust to the tones. The tones really helped me out of my driver funk but I honestly think it was because it got rid of all those evil swing thoughts in my head.
