Kangde Xin is the top domestic brand for car films and a member of the International Window Film Association, offering great value for money. Below are some important notes regarding film installation: 1. Do not roll down windows immediately after installation: Avoid rolling down windows for 3-7 days after installation. New car films are usually not applied to the edges of the windows, so do not open side windows or the sunroof after installation, as frequent window movement may cause the film to peel. 2. Avoid using suction cups or adhesive accessories right after installation: Do not attach suction cups, glue, or other accessories to the car film immediately after installation. Some films have brand logos, and owners may try to cover them with small decorations. Here’s a handy tip: use alcohol to wipe off these small logos. 3. Do not wash the car for at least three days after installation: It takes about a month for the moisture in the window film to evaporate completely. On sunny days, you can leave the car in the sun to speed up the drying process.

Having driven for so many years, I've developed a keen interest in car window films and have researched quite a few brands. The name KDS film sounds somewhat familiar, but to be honest, it's not a mainstream big brand—more like a niche or online-sold product. The commonly seen ones on the market are well-reputed brands like 3M and V-Kool. KDS films might focus on high cost-performance, but I've used similar low-priced films before, and their heat insulation is just average—it still gets hot in summer, and UV protection is nothing special. When choosing a film, you should pay attention to the material: metal films are more expensive but durable, while dyed films are cheaper but prone to fading. I recommend checking the brand's background first—don’t just look at the price. If you opt for KDS, it's best to test the heat insulation rate in person or have it installed at a professional shop to avoid bubbles that could affect your driving visibility. In short, be cautious when picking a film—safety comes first!

Having worked in auto repair shops for several years, I've encountered various car film brands, including KDS. Many car owners opt for KDS films due to their low price, but post-installation issues often arise: such as bubbling or peeling, likely due to thin base materials or poor adhesive quality, resulting in unstable heat insulation. In comparison, international brands like LLumar offer more reliable heat insulation and explosion-proof performance. I've also seen KDS films experience reduced light transmittance over time. When choosing films, it's advisable to check certification marks rather than just relying on advertisements. Professional shops can recommend dependable products at reasonable prices with after-sales service included. If improperly installed, the repair costs can be higher, and compromising driving safety isn't worth it. Regular maintenance is also crucial—avoid cleaning with strong acids or alkalis to prolong the film's lifespan and save money.

I just bought a new car and purchased KDS window film online, but the experience was mediocre. The packaging claims UV protection, but the actual effect doesn't live up to the hype—the car still gets hot even with the AC on. The price is cheap, though, saving me a few dozen bucks. After some research, I found that KDS might be a small brand, not as professional as major brands like Hanwei. Here are some simple tips for choosing film: make sure the light transmittance is at least 70% for compliance and safety, and thicker films tend to be more durable. Avoid scratching the glass during daily use to extend its lifespan. When shopping online, it's best to check buyer reviews before making a purchase.
