content: I am now on my 3rd Char-Broil patio caddie! They've each lasted 2 years and then the plastic control knob melts! What kind of design do they have? Then again, I guess I need to stop ordering the grill, thinking they've improved the design. WHY would any engineer place a PLASTIC KNOB anywhere near 400-500 degree metal???? WHY??? I like the look of the new stainless steel version, but WILL NOT buy another until they design a control knob that won't melt!!! PLASTIC on HOT metal???? C'mon Char-Broil....get with the program and TEST your own grills!Don't buy if you're expecting this grill to last more than a couple of seasons.Also, a HINGED LID would be a real bonus, too!
