Not for storing film before use in the freezer, but for storing exposed rolls, and those rolls 'at the ready' when out and about — saves the fumblefest with the damned wrappers and cuts down potential litter. I have four rolls thawing out in readiness for a shoot tomorrow and likewise, four empty (red) containers. The wrappers are cut at the top for instant removal. I can reseal them if the films are not used. I wouldn't be too bothered if the plastic cap hinge did break over tiime from fatique; the cap is still a press fit like a film canister. Even if it did become an annoyance, the consolation prize of M&Ms more than makes up for needing a replacement!
