My window tinting still looks great after 2 years. My car was taken to a different shop a couple times before it was brought here. The other shop did a terrible job and left multiple bubbles and jagged edges. Auto Tint of Dublin did a fantastic job in just one day. No bubbles in the tint and all the edges are perfect. I don't know about the cost because our car dealership took care of it. The only thing is that they couldn't do as dark of tinting as I would have liked.
