Protective Film Quality Evaluation Guide
1. Observe the texture of the material
High-quality: The material feels delicate and smooth, without rough graininess. It rebounds quickly after bending and doesn't crease permanently. Resists scratching and has good toughness.
Inferior: Feels stiff, tears easily, scratches show visibly. Contains more impurities, has poor light transmittance, and may have a pungent odor.

2. Test the protective effect
High-quality: Effectively blocks scratches. Liquids slide off quickly without penetration or residue.
Inferior: Absorbs stains which become difficult to clean. Stains may penetrate and affect the mirror surface.

3. Check the performance of the fit
High-quality: Fits tightly with minimal bubbles that are easy to remove. Edges stay firmly in place without warping.
Inferior: Produces many hard-to-remove bubbles. Edges warp easily with uneven viscosity (some areas too tight/loose).

4. Inspect the durability
High-quality: Performs well in extreme conditions without deformation, yellowing, or losing viscosity. Leaves no residue when removed.
Inferior: Ages/cracks quickly in harsh environments. Loses viscosity fast and leaves stubborn glue marks.
