Brand reputation and influencer credibility
Multiple reviewers mention purchasing after hearing about the KAIST professor creator on podcasts, indicating strong trust-building through expert positioning rather than traditional influencer marketing.
Product variety exploration

Conversion to repeat purchase
Several reviewers indicate they purchased the kit, tested it, and subsequently bought full-size Grabity products, suggesting the discovery kit successfully converts trial users to paying customers.
