Product review (5 stars): Excellent quality
It is the same product as "Whirlpool W10712394 Adjuster KIT".  It seems to be very well built and durable. It can be easily replaced after watching the video https://www.youtube.com/watch?v=otUn8eoceBw. Be careful when installing the adjuster body as there are two small plastic tabs at the bottom which can break easily. Kit includes a Phillips to 6-lobe adapter and hence no need to buy the Torx screw driver.
