Actually, Con, Formula One's product is just as good. I did my research. Formula One's Pinnacle (all ceramic) tint at 35% (and legal here in Texas), has high optical clarity and heat rejection of 52%. There was a big disparity in price between the two. So, I emailed the Huper rep locally and this is what he had to say as to why I should buy Huper:
Dawn, I'm very glad to hear that you have been researching Huper Optik window film for your 2005 Mustang. Huper Optik is a designer window film. Created by German technology. It is very specific and controlled. One film. One company. One Goal. Using ceramic technology to insure maximum heat rejection while supplying optimum optical clarity. If you do not want a dark mirrored product on you glass, Huper Optik is your choice.
Wish you the Best,

Bottom line - one word - "designer". Is designer superior and worth the difference in price? Negatory. Oh, and I could've gotten Huper cheaper by a Mother's installer who offered to do it for me "on the side" but it wouldn't have come w/a lifetime warranty.
Get over it with the Germans, already. And yes, that is an ORDER!
