Llumar tint is top of the line tint. I had 5% in the back and 15 % up front. I'm not quite sure why people say it is hard to see out of in the city. It may be harder to see out of if you live in the country, but I have no experience with that.
I bought a tint install kit with precut window tint from ebay and the install went great i did it on 2 vehicles i did 20 percent on the front and 5 in the rear... all together it was 50 shipped for each vehicle...
