Product review (2 stars): Economical Fix/Poor Plastic Design
Worth the money, easy install.
Five months after install, the plastic support arm cracked (left side). Poor design by KitchenAid/Whirlpool. I have ordered a stainless steel replacement from Amazon, Whirlpool W10712394 Adjuster KIT, and will install upon receipt.
Ordered on a Saturday arrived on Monday and installed new metal adjusters in under an hour.
