I just had 35% Llumar IRX installed and I like it. I've had Llumar CTX installed on my oldest vehicle since 2010 or so. I had three other vehicles tinted with CTX over the years.it's been perfect and still looks as good it did when it was put on. No issues, no warranty issues, no complaints. My installer prefers Llumar over their Pinnacle and FormulaOne stuff. He says less issues, but also says the number of complaints may have to do with the people choosing the more expensive stuff. He only carries Llumar now and have for a few uears now.
