The artwork from Brad is awesome. The material he uses is INCREDIBLY forgiving. I probably stuck/unstuck parts of it a dozen or more times, and it never lost its adhesion. It's also really easy to get air bubbles out of it. The 'air release technology' really does work. It seems like really tough stuff too. I think it will last a very long time.
The material aside, the printing itself is also top-notch. Nice vivid colors.
The only issues I had were self-inflicted. I didn't get a couple of the pieces on as perfectly straight as I would have liked. So learn from my mistake; take your time, and get an extra set of hands to help.
