The Tint Wizard tinted the windows of my four door car. The tint job was perfect, I had no complaints. However, one day when I went on base I was told that my tint was too dark. According to the mp's tint reader it was a percent or two too dark. At Tint Wizard it read right on. I was ticketed and had to take the tint off to get rid of the ticket. I went back to Tint Wizard and they took the tint off for me, and re-tinted the windows to make them lighter. I went to get the windows tested and the mp's still said they were too dark! It turned out that my windows already had some tint in them from the factory and that's what was throwing it off. I had to get the tint off AGAIN and brought the car back in to the mps with no tint on the windows. The Tint Wizard then tinted my windows one last time. I was amazed by the patience and great customer service of tint wizard. They ended up tinting my windows three times and only charged me for the first time.
