Heights has a well-structured product page with strong above-the-fold social proof (5,887 reviews, GQ press quote in hero) and clear benefit copy, making Clarity its strongest dimension. The single most critical gap is the absence of a sticky mobile CTA combined with a PSI score of 43 — cold mobile visitors face a 6+ second load and then lose the buy button the moment they scroll, creating a compounding conversion leak that undermines an otherwise credible page.
No customer photo reviews or UGC are visible on the page. The single featured review from 'Jay' is text-only. Photo reviews from real customers would materially increase purchase confidence for a supplement at $48/month.
