Good value for money. See over time to the wear rate but the one I received from seller and storeman is a certified piece and manufactured by Whirlpool Corporation. Contrary to what has been said previously, do not use a wrench to remove the part to be replaced. With a simple screwdriver, simply lift the edge of the part to be replaced and remove it as a bottle cap before screwing the new one in the opposite direction of clockwise and as explained in the instructions that the accompanying. I would recommend ordering one piece without the wrench to 6 instead of the one with the key to 14. In order two also to pay only once the delivery charges and be one step ahead because it is a piece must be replaced after a certain number of uses. Attention to the chosen supplier as some charge the shipping charges to the room and others to send.
