This review is hard to write, as I feel that they do decent work - just be careful of their advertising practices.
I bought a Groupon to get my car tinted - it was a good deal at $119 for "all 5 windows" as advertised. When I arrived, they informed me that each little side window counts as separate windows, and that my car actually had 9 windows. Not only that, but I was not allowed to choose which windows I wanted to tint - the groupon would only cover the "back-most 5 windows". That means that my front side windows and back side windows would not be tinted, just the little quarter windows and the back one. They offered to tint my remaining side windows for $100 more.
Also not mentioned on the groupon is that you don't get to choose the darkness of the tint. Only 35% film. I had originally wanted to go 80%, but I was told that the groupon offer is only good for the 35% - again not mentioned anywhere on the ad.
I went ahead and paid the extra $100 so that all my side windows and the rear would get tinted, and agreed to go 35% on all windows (not that I had a choice). I'm actually pretty happy with the work they performed, but can't help but feel a bit cheated due to their advertising malpractice - felt a little like the classic switch and bait to me.
