Are wire shelving closet kits like Rubbermaid Configurations strong enough for a full wardrobe?

Across r/HomeImprovement threads we read, long-term owners report Rubbermaid Configurations and similar wire kits hold up to years of normal use as long as the rails are anchored into studs or with proper drywall anchors. Reviewers consistently flag that the weak link is installation quality, not the hardware itself. Heavy coats and dense hanging loads benefit from extra wall-mount support brackets.
