Product review (5 stars): Great spring.
This spring arrived promptly, well-packaged, was brand new and shiny, and fit perfectly.  It happens to be a very strong spring because of what it is expected to support - the heavy dishwasher door, so it is not easy to install alone.  It helps a lot of one person stretches the spring to the length needed to reach the chosen hole in the side of the door, and holds it at that length while the other person inserts the hook of the spring through that hole.  Then, you're finished!
