I’ve had one take 4 days. Clipped it to a magnet and put it on the frig to remind me to call the LHBS, then it swelled. Must have been the heat from the frig. Examining the package showed it several months old. My lHBS told me that the old date on the package does not represent it’s real age but some other factor …just silly talk. I buy it at NB now and have not had any such problem at all.
