i would say windows tint is a very personal thing .. one might have good experience with one and might not apply to everyone .. depends on luck

as for myself .. just got my civic tinted with Aircool Duroguard 4mil safety + solar control film .. front windscreen is with the top range 98% heat rejection and smart tag friendly .. whereas all side windows and rear is with the 4mil safety tint which claimed to reject 88% of heat .. the tint is quite dark and up to my liking as well .. if not mistaken VLT is 45% only .. BUT summon is covered by Aircool

price can be range from 1.4k - 1.6k depends on which windscreen tint u choose .. if you are interested can PM me .. i will give u the salesgirl number as im quite closed with her
