The Knob Stopper -Stove Safety Starts Here- (Our Product is Patented) is a safety product for gas and electric stoves, which prevents the knobs from turning accidentally and reaffirms they are in the off and locked position. It will also give you added reassurance that your stove is off when you are not around. You'll never have to second-guess whether the knobs are in the off position or worry about pets and children accidentally turning them on.
