I had neuvision before on my front windshield for an older car of mine.
I needed new tint because my old one was fading. that car had bad headlights so i needed to be able to see at night. so i opted for light/neutral neuvision tint.
it was ok naman, i had that tint for about 2-3yrs before i sold the car. and the tint was holding up still. no fade, no changes, looked bnew still. for dark neuvision tint..i cannot vouch for though. I think the difference between neuvision and 3m and other brands wasn't much. might as well go for a brand with reputation already..unless you're willing to give Neuvision a try and make a reputation for it hehe.
