Product review (1 stars): DANGEROUS, DOESN'T ALWAYS TURN GAS OFF PROPERLY.
Seemed fine at first, but after only a few weeks, when you turn the knob, it is like a stripped screw and just turns and turns and you can't get the gas to turn on or get to the right level.  This caused a BIG problem one day when we kept smiling gas and then determined that the knob hadn't turned the gas all the way off!  DON'T BUY--THIS PRODUCT IS A POTENTIAL DANGER.
