1. Professional Installation

• After-Sales Support & Warranty: Backed by comprehensive warranty and service. Issues like air bubbles, scratches, or film degradation are professionally repaired or replaced.
• Quality Assurance: Installed by certified technicians using professional-grade tools, ensuring a seamless fit with no lifting edges or air bubbles.
• Hassle-Free Convenience: Eliminates the need to prepare dedicated workspaces, specialized equipment, or precise installation setups.

2. DIY Self-Installation

• Cost Savings: Saves on professional labor fees, though materials and specialized tools must be purchased independently.
• No After-Sales Support: Any installation flaws, premature wear, or aging issues must be resolved entirely on your own.
• Quality & Execution Risks: Without professional expertise, risks like trapped air bubbles, edge lifting, or uneven surface finishes are significantly higher.
