Some have had concerns or issues with fit or finish, some have had great results, from my personal experience, I've had no fitment issues that couldn't be resolved, minor in nature if any at all, I have had no issues with any of the finishes as long as your looking for an OEM example of chrome, most are spoiled looking at triple chromed (copper/nickle/chromium) "show" bumpers over the years, the AMD finish is the same as stock OEM finish, nickle/chromium, B body AMD bumpers seem relativity sound as far as fit/finish, the E bodies are somewhat prone to fitment issues
