Thanks everyone for your insight. I think I started taking a "magnifying glass" to my windows because I first discovered the tint on my back glass was curved and not tinted past the dot matrix in some parts (see below). When I had them redo the back glass a couple days later, they pulled off some defroster lines -- very poor start.
I guess what is bothering me about the windows in my original post is the unevenness of the gap across the window edge when I specifically asked them beforehand if they could tint to the edge (or if they shaved/filed to the edge), and they assured me that they did. Given that context, do folks still find the job acceptable?
