Product review (4 stars): The belt worked fine, fit fine
The belt worked fine, fit fine.  It is a very tight fit, and a bit tricky to install, but that's the point of a drive belt.  It appeared identical to, but much newer than, the original belt.  I won't be able to comment on it's long-term performance - soon after replacing the belt, I decided to replace this very old dishwasher entirely.
