@Kevin L - Yeah, because the majority is always right aren't they? Weber puts cheap and effectively useless analog thermometers on their grills because that is what the majority of buyers expect to see. I have yet to find a single one of these thermometers that is accurate to begin with and, more importantly, maintains that accuracy. More important, because if it at least maintained its inaccuracy, then it could be used for relative measurements...but they don't even do that.
@Matt R - Taking liberties? Sounds like you own a "thermometized" grill. Sorry about your luck. As Harry Soo likes to say, "BBQ is ready when it is ready!" Implying, or course, that the BBQ cooking process is not an exercise in scientific precision. I guess he is "taking liberties" with such a statement.
