Blister Pack Frustration
Sealed in hard plastic requiring scissors or knives; tears are uncontrolled and messy, often damaging the pack.
Accessibility Barriers
Excludes elderly users or those with arthritis, tremors, or limited hand strength. Assumes two-handed coordination and perfect vision.
Zero Resealability
Users typically need only one or two batteries at a time, but packs cannot be closed back up, leading to loose, misplaced items.
