Just received my set today and so far everything looks great. MTK is great to work with, fast turn around.(two and half weeks) and like anything vacuumed formed, the thickness of the armor varies from part to part but thus far nothing too thin or appears to be weak. Like others stated above, butt joined with cover strips for accuracy.
Details are sharp for the most part.
I look forward to putting my first set of armor together over the next several months worth of weekends.
