Are filament vacuum bags worthwhile? (sh.itjust.works)

I finally got a filament drying box and I'm using it prior to and during prints. It seems to be helping. I'm a bit of a color queen, so I keep a pretty big backlog of different filaments. I've been storing them in vacuum bags but the vacuum bags often seem to lose some of their vacuum after a few months; the whole process is a bit of a pain. Is this really worthwhile or as long as I'm using the drying box can I forgoe the vacuum storage? If vacuum storage is still a good idea, are there better bags I should be looking for that don't lose some of the vacuum after a few months or is that pretty standard?

I wouldn't bother with vacuum bags If I were you. I think it's fine if you're using a drying box after the filament has been sitting out a while. Doesn't hurt to try and find out at least...

Personally, I just use a big plastic storage bin with a bunch of silica desiccant in it. I just busted out some polycarbonate (notoriously hydrophyllic) recently that had been sitting in there for 4+ months and printed straight away; no stringing or anything.
