Specs wise Vkool is right there on the top. However, the films suffer from demetalization where you will see streaks of lines on the film starting from year 5/6 onwards and gets worse. Performance also drops over time. 3M and HO does not have demetalization issues, but cannot match Vkool specs when new.
I have used vKool elite for many of my previous cars, and have experienced the demetalization issue with the film.
BTW, both Vkool and Huper Optik are abang-adik company with parent as Solutia Inc. Previously both of these films were developed by Southwall Technologies Inc. USA and were acquired by Solutia Inc in 2010. VKool first (older gen) then the Ceramic range (Huper Optik).

Yup, agreed and thanks for the information. As currently most of the tint out there can't even give you warranty more than 5 years and to be honest my old Llumar start demetallization started from 2 year onwards, how i know? The color of the tint start fading that how it is... and most of the tint does as well. Please take note VKool will also having the same issues but i don't expect to last more than 5 years as well. It just depends on your own preferences as well.
