I received them yesterday.  They were cheap and they did not work with my range although they advertised that it would.  I went to send it back and was notified that this product does not allow returns.  The tabs have "off" on it upside down on a loose piece of cheap foil paper and there are no other markings.  They are made of cheap die cut plastic and they will not allow the knob to depress to access the gas to start the burner.  I am so unhappy with Amazon for selling these an it will make me think twice before purchasing anything again.
