  • Warranty90-day return policy[1]
  • Repairability1/10[5]
  • "Score 1/10: This item is a single piece of molded plastic. It cannot be repaired. Sanding plastic boards creates microplastics and uneven surfaces. Must be replaced when deeply scarred or warped."

    "Plastic commercial boards typically last 2-4 years in heavy use before scarring requires replacement"
Materials & Specs
Last Verified: 3/12/2026
Data Quality Note

"Deviated from standard baseline maintenance cost ($5.00/yr) because poly boards do not require the mineral oil used for wooden boards. Lifespan is estimated based on commercial kitchen consensus for plastic boards."

Compliance Statement: All technical claims are traced to manufacturer documentation or independent material analysis. Financial projections are based on these verified inputs.

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.
