Product review (4 stars): Authentic dishwasher replacement straps
I bought these to replace the straps that had finally failed on my dishwasher.  The previously failed strap caused the door become dead-weight, slamming open if it was not held all the way to the floor.

Replacement was simple: there are a number of videos on YouTube that will walk you through the process of removing the cover beneath the door, unhooking the existing straps, and attaching the new straps to the hooks and the spring that runs between them.
