However, buyers must account for moderate-to-longer lead times (2–6 weeks), higher upfront costs ($10,000–$15,000), and critically, must vet their local authorized dealer thoroughly and obtain warranty terms in writing before purchase. Warranty disputes and inconsistent dealer service are documented risks that can significantly affect the post-sale experience. If rapid installation, budget constraints, or absolute warranty certainty are priorities, alternative modular systems (Acorn, Bruno, Harmar) may be better fits.
