Product review (5 stars): The real deal
Don't bother with other, cheaper replacement sets. I read the reviews and I don't have time for stuff that doesn't work or fit or last. The isntructions were easy to follow and everything went right into place. The hardest part was getting the original plastic retainer triangles for the drum roller off.  I just ended up cutting them.

This was really an improvement over my model's original equipment as mine did not come with a tension roller.  The original tensioner was just a curved metal channel on a spring so the belt rubbed against it constantly. Even so, the original belt lasted over ten years.
