4.3 Selling Point vs. Decision Driver Alignment

4.3.1 Alignment Analysis

Mainstream selling points like 'ease of use,' 'water purification,' and 'mineral deposit prevention' generally align with core user decision factors, driving market demand. However, misalignment exists between market claims and user experiences regarding 'actual cleaning effectiveness' and 'ingredient safety.' Despite ubiquitous claims of 'white dust removal,' 'mold prevention,' and 'non-toxicity,' reviews reveal inconsistent results-with some users reporting new residues or ingredient concerns. This gap between compelling marketing and inconsistent user validation highlights stability of results and ingredient transparency as critical market pain points, creating substantial opportunities for solutions that authentically resolve these issues.

4.3.2 Key Findings

• Actual product performance lags behind user expectations, especially regarding white dust and mold suppression. Despite marketing promises, uncertainty about effectiveness sustainability causes polarized reviews, damaging brand trust and repurchase rates.
• Ingredient transparency and safety represent deep-seated user concerns, particularly in family/pet contexts. Consumers question whether products are truly 'non-toxic,' limiting market penetration in health-conscious segments.
• Size compatibility is an unaddressed pain point directly impacting unboxing experiences. Returns/negative reviews due to product-waterport mismatches represent avoidable issues, highlighting unmet needs for precise sizing or universal designs.
• Playful designs attract initial interest but core functionality remains crucial for retention. Characters like fish/submarines provide differentiation but cannot retain users if cleaning efficacy is inadequate-potentially generating negative feedback due to functionality gaps.
