I've (unfortunately) had to use their services twice so far and both times I was very happy with the service. The guys in the shop were very courteous and I wasn't at all skeeved out. They also worked really fast. If you call ahead of time they can tell you if they have your window in stock and if not, they can order it and you can come by when they have it so you don't have to be without a car for too long. Then they replace your window while you wait-- it's so fast! and they even vacuumed out the shattered pieces of my old window.
