When I moved from CA to NV in 1999, we went from a place that had a fair amount of year round humidity to the high desert that has very low humidity most of the time. BEFORE the move, all my humidors did OK. Once we hit the dry climate, I soon found 3 of my lower end humidors had warped from the dryness and no longer sealed proper.
Due to my buying habits, I recently had to bring a couple low end desktop humidors out of retirement. They seal OK but being low end, they are cheap and I know I have to use more than the normal amount of humidification media.
