Product review (5 stars): So this was a great savings and so far a few months with it ...
It is the correct belt for our Frigidaire Affinity Washing machine but when it arrived it was truly about 6 inches shorter than the old belt.  I can see how & why people think that it is not the correct belt (assuming that you have matched the part number exactly or it's replacement).
I do not repair washing machines for a living so for me it took about 20 minutes maybe for to work & try to evenly stretch that belt out so that it could actually make it around the flywheel.  I would not be surprised if there isn't a tool or device that makes this a snap to do for the pros but if you aren't I am trying to get across that it took some time and patience to working it on and attempting to get it fully onto the wheel.  It's thinner than a car v-belt, but then you don't have to make those stretch an extra 6" either.

Hopefully this will last a long time, and if in a few years if the machine is in need of another one i hope this seller is still around with them in stock.
The local parts places and the Frigidaire warehouse wanted +/- forty buxs for this.  So this was a great savings and so far a few months with it and all is well.
