Can the car film given by 4S stores be used?

This depends on the situation. Some car owners who are not very particular may accept it. Here is the relevant introduction: 1. Benefits of film: The benefits of film include blocking ultraviolet rays, heat insulation and sun protection, preventing the car's interior from being exposed to the sun, and providing a certain level of privacy protection inside the car. At the same time, car film can enhance the appearance of the car, improve the texture of the car, reduce air conditioning energy consumption, thereby lowering fuel consumption and saving some expenses, achieving the effect of saving fuel consumption. 2. Types of car film: Car films can be classified into ordinary film, sun protection film, explosion-proof sun film, etc. In terms of color, there are also different types such as natural color, tea color, black, sky blue, gold ink, light green, and color-changing.
The tint film on my car was a freebie from the 4S dealership when I bought it. After two years of use, it doesn't seem too bad—after all, it was free, so why not use it? The sunshade effect during summer driving is just average; the window glass still feels a bit hot to the touch, but cranking up the AC gets me through. The privacy protection is decent; it's not easy to see inside from the outside. The downside is that after about half a year, it started to fade a little, and small bubbles appeared at the edges, but it doesn't affect normal use. I asked a mechanic, and he said the films given by 4S shops are usually non-branded products with low costs and ordinary materials, resulting in a shorter lifespan. If you care about heat insulation and durability, it's better to spend a bit more and get a branded film installed yourself. But there's no harm in trying the free one first—if issues arise, you can always replace it later. This way, it's hassle-free and cost-effective, and there are no major problems for daily driving.
I've been into cars for over a decade and am quite particular about window films. The films provided by 4S shops are basically entry-level products with mediocre quality—low light transmission and poor heat insulation. Even on summer highways, you'll still feel the heat. Compared to the professional-grade film I bought later, there's a huge gap in performance. The free films are mostly made of ordinary dyed PET material without special treatment, prone to aging, fading, and bubbling over time, which affects both appearance and visibility. Don't expect much from them, but they're free and can serve as a temporary solution—providing some shade and privacy when newly installed. If you frequently drive long distances or are concerned about UV rays, it's better to skip the free film and spend a few hundred bucks on a high-performance metalized heat-rejecting film. The effect is immediate, significantly reducing skin darkening from sun exposure.
