I received mine on last Friday and gave it a workout on Saturday. I think it still requires a bit more shaping to fit my face as comfort was a minor issue. (I have a big nose.) I also had a bit of difficulty looking down my AK's sights. However after taking a direct hit to the mouth area (It made a wonderful "CLANG!" sound.) and hearing about a couple other players who took rounds in the mouth, I'm inclined to say that while not totally perfect, this is going to be part of my basic kit.
