Because unless I misunderstood, I'm saying in my experience you do need to use a humidification device in a tupperdor, or at least keep an eye on them regularly.
Not Sistema, but a mix of brands that have the gasket system. Perhaps that was my issue. The main point I was making is that don't assume your cigars will be ok in a year or two in a tupperdor without checking.
I quite agree, once they are stiff they go in the bin as they never work properly if you try to recharge them again.
