I also pay close attention to how easy it is to install, because a difficult setup can turn a good product into a frustrating one.
My Priority: Film Quality
For me, the quality of the film is one of the most important factors. I look for strong light transmission in clear mode, reliable privacy in frosted mode, and a smooth appearance without bubbles or cloudy spots. A high-quality film usually lasts longer and gives a cleaner, more professional finish.
Checking the Switching Speed
