  • Original boards are made to meet strict OEM standards.
  • Aftermarket boards may have varied quality and reliability based on the manufacturer.

Warranty Differences

The warranty offered on a product can provide insights into its longevity and manufacturer's confidence.

  • Original boards typically come with longer warranties, often 1-2 years.
  • Aftermarket options may offer shorter warranties, reflecting their perceived durability.
