According to the Official 3M Pamphlet for Crystalline, they advertise that their film blocks up to 60% TSER (total solar energy) and 97% infrared rejection* [<with that asterisk!] The asterisk indicates a “fine print” which is at the bottom of the pamphlet. *Infrared rejection measured on film only from 900nm-1000nm. Most customers don’t know that this means the 3M company used a portion of the scale to make their numbers appear higher than they actually are. What does that mean? It means that you are not getting the heat rejection you expect to get when you’re paying $500+ dollars on this film. Many customers find out the hard way about how this film does notblock out the heat they expected. In fact, it starts to blur after a few months of cleaning since the color coating is on top which comes off looking at it installed from the inside. Take a look at this video to see how easy it is to remove the color from the Crystalline film. Many unhappy customers have left negative reviews on the 3M website as well as on Blogs & Forums including the Tesla Forum. 

Huper Optik advertises that they test all of their films including their famous Authentic Ceramic Film on the FULL heat spectrum of 2400nm. There is absolutely NO alterations to their results. The TSER/ Heat Rejection that they advertise is true and happy customers agree that they are getting what they paid for! The Ceramic film by HuperOptik is one of the most durable on the market, and provides the highest clarity with no deterioration from cleaning or sun exposure.
