Product review (5 stars): Perfect replacement, fixed our washing machine
The agitator in our washing machine stopped turning after washing a rather large load.  It turns out that the teeth on the "dog ears" (the four little plastic pieces)in the cam were stripped, which happens with years of regular use.  The cam makes the agitator spin in one direction, but with the teeth stripped, it would move back and forth, which doesn't properly wash the clothes.  It is easy to assemble-comes with easy to read instructions-and the build feels durable and the material is high quality.  I was able to find a video on YouTube that showed how to replace the cam on our specific washing machine and it's a very simple DIY project.  Glad it was such a cheap fix, too!  I'm sure our washing machine and new cam will last for many more years to come.
