The impression that I got at the store was that the humidifier had simply run dry. The last stick I bought there was less than a month ago, and it was fine, so I don't think that they were at 55% for
too long. The hygro looked to be a high end digital; so I don't know how far off it might be, if at all. They don't carry high end sticks, which is why I was there and not at the B&M. At this point I'm mostly buying daily smokers, so I just may roll the dice. Thank you all for the good advice, but if anyone has more to offer, please feel free.
