Hello, the logo usually attached to the film is the brand of the film, but the film you attached is not a brand film, and it may just be OEM OEM on behalf of the processing factory. As for the quality, it is really difficult to estimate, just look at the speed of its fading. If your film does not fade for five years, it is worth comparing. Also, see if there is reflection at night. The quality without reflection is much better than that with reflection. The most important thing of the front baffle film is anti-glare.

PS, I'm a movie wholesaler. Many times our factory will do OEM work for the following wholesalers, so I know something about it. Good luck.
