I am about to get my 3’s window tinted. I called around for quotes from several shops that are all within a few dollars of each other. The shops use different films by major manufacturers, Suntek, Llumar, etc. Assuming I am considering the top of the line film each manufacturer makes my gut feel is that they are all roughly equivalent good products and that this really comes down to which installer I like. Am I reading this wrong? I know that some of the manufacturers frequent this board so I’d welcome their insight.
