The page did not declare, in writing, who the buyer was, what the buyer's existing failure mode was, or what the post-purchase outcome looked like. Three sentences, none of them present. Every other defect in the case file is downstream of those three missing sentences.
The product description was a feature inventory. Features earn buyer trust after the buyer has decided the product is for her. The page was running the feature inventory before the buyer-state assertion, which is the inverse of the order a buying decision actually moves through.
