Does it concern you at all that they don't disclose how much improvement? I guess (too late) I've become more distrusting and am wondering if perhaps between 6 months and 9 months there was deterioration. Of course I could be making a mountain out of a mole hill and they could just be saving the data for a medical conference.
Congrats on your nice investment! Wish I would have got it when it was in the 1 range but I was too chicken to buy most anything then :-)
