Product review (5 stars): Good Kit. Good Project.
Our Kenmore machine was squeaking -- it is pretty old, but this kit renewed it.
The new belt is good too, because the old belt was pretty frayed - it would have broken soon, no doubt.

I think the machine runs better too - I suspect that the belt was a bit stretched out, and I believe that this could lead to drum slippage.

The project did take an hour or two -- the video tutorials you can see on YouTube were helpful in my opinion.
