For some this could be a nice system, although I agree with Pat that a CI skillet works just fine. Also, the searing grate I guess is for those that are challenged by the tricky diamond patterns. Just turn the meat twice on each side and you'll get a nice pattern. The wok has some merit in that the grate appears to hold the wok in place. It's after the cook that it may pose a problem. In the video, the wok is removed from the grill with the food still in it. Where do they place the wok once inside? Without a cooking ring, which is standard with a basic wok, the wok isn't stable.
