Note: The privacy effect of the window film will vary with the change of light and angle. The mirror effect means it has a slightly reflective effect, not totally like a mirror. The different effects between daytime and night: The outside glass will show a mirror effect as well as keep your privacy during the daytime. At night, the outdoor glass will lose the mirror effect, and people outside can see Inside. Therefore, curtains are necessary at night. (Reasons: The side with stronger light will have a mirror-like appearance, while the other side will be see-through. This means when indoor light is stronger than outdoor, people outside can see people inside. In general, people outside can't see people inside during the daytime)
