1, Gu Wei: Needless to say, it is an expensive membrane recognized in the market at present, and its heat insulation effect and ultraviolet protection effect are really good. Aside from the price factor, its film texture is soft and scratch resistance is not very good. As we all know, the curvature of the side window of the new Accord is large, which is easy to cause serious scratches on the film. At present, the front gear plus the car body should be able to bid 2500-3000 yuan, which is not worth it. 2. Johnson & Johnson: The price/performance ratio is good, but now fakes are rampant in the market, so it is difficult to distinguish. Johnson & Johnson's new security label was copied. However, Johnson & Johnson has a hard texture and good scratch resistance. At present, the front gear plus body should be around 2000 yuan. 3. Ray-Ban: Many users, good quality, but few real goods. Only authorized franchisees have genuine goods. Current price: front gear plus body should be around 2000 yuan. 4. Dragon Film: This brand is very loud and the quality is really good. However, because it has just entered the market and the price is high, the sales volume is not very good, and there are few agents who make this brand. Current price: 2500-3000 yuan. 5.Nanolux: Although its popularity is not very high, its cost performance is good, its light transmittance is good, and the most important thing is that there are not many fake and shoddy products. Current price: front gear plus body 1600 yuan. 6, 3M: The same fake film is everywhere, with less color, but the real film is also a classic, and the effect of filtering ultraviolet rays is also good. Current price: front gear plus body is about 2000-3000 yuan. 7. DuPont Veyron: It entered the market relatively late, and it is a rising star with high cost performance, good scratch resistance and light transmittance. Current price: front gear plus body 1500-2000 yuan. For details, please refer to www.lg-china.com.cn 8 official website. Yuma: This brand belongs to the mid-range. Because it entered the market late, its popularity is not very high, but its effect is good and its scratch resistance is good. At present, manufacturers have controlled the supply of goods and delivered them to authorized stores. Basically, there are few counterfeit products.
