Product review (5 stars): "Exact Replacement" Is Not Hyperbole :)
This is the sort of thing that used to be the reason for existence of hardware stores:  I was unable to find a single local hardware store that stocked something so exotic as a dryer belt! :).  I have only had it in for about a month, so I can't comment on long-term reliability, but the product fits, and looks the same, so, so far so good :)
