Product review (3 stars): Didn't fix the problem
My dishwasher was leaking.  I purchased this gasket hoping to make it stop.  There weren't really any installation instructions, and the seal is either too long or too short, depending on if you stretch it while installing.  I kept pulling it out and putting it back in, each time stretching it differently, leaving a lot or a little at the ends.  I guess I didn't understand what to do with the excess length of seal.  The old seal was just kind of wadded up at the end, and it worked like that for many years.  That is why I wanted instructions.  I ended up buying a new dishwasher.
Having said all of that, it is a high-quality seal, and it would probably work just fine in somebody else's dishwasher.
