Quality is important with nearly everything you can think of. I know that people pay a lot for quality for things like basic products to things that are more of an investment like cars. If you are paying all that for something like a car, I think that it makes sense to buy something high quality to keep it safe like quality window tint. One that I think of right away is 3M window tint Austin. They have an entire line of different tints. These tints range from your typical dark tint to a very light tint that allows more light to come in. All of them keep a lot of heat out of the car to keep it cooler. They are also nonmetallic so that they don't interfere with any wireless signals. These are high-quality products that require professional installation from a car-tinting specialist. However, once they are carefully, quickly, and properly placed on the car windows, they are there for quite a while. The car will look cool, feel cool by keeping the glare and heat out. I have had good experiences with 3M products. I wouldn't doubt that the great quality in their other products would translate to their window tint line for cars. I know that if I had a car, I would consider getting their tint line.
