LIMITATION OF LIABILITY: This audit is a financial projection tool for informational purposes only. All cost estimates, lifespan predictions, and durability assessments are based on historical data, manufacturer specifications, and statistical modeling—not guaranteed outcomes.

TECHNICAL SOURCING: Technical specifications (e.g., material composition, IP ratings, warranty terms) are sourced directly from manufacturer documentation, patents, and publicly available material data sheets. While we verify claims against material science principles, we cannot independently test every unit for manufacturing defects.
