Like i said before, "this place blows me away." Had my tint done with 15% all around CTX ceramic. Although it made a HUGE difference with the inner temps, the CTX actually looks a bit lighter in shade color (than the other series they carry). I drove my truck home and realized that it was the same shade all around. I actually thought the back would be bit darker, being that the back windows are a hint darker from the factory. Spoke with Mike (owner) and he said, "not a problem. Just bring your truck back and we'll make it right.... at no additional charge." How amazing is that.... SUPER!!! If you want SUPERIOR SERVICE and QUALITY, EcoTint is the place. They stand 200% behind their product and company standards.
