Mid-pack minimax-m2.7 Cedar & Sage — DTC product page
70/100

“Visual design fails due to a severely broken, non-responsive mobile layout with horizontal overflow. Hero copy is clear and benefit-led, but the 'customer' section awkwardly repeats product features instead of providing testimonials. Grounding is excellent, strictly adhering to provided facts without fabrication.”
