Product review (5 stars): It works
I bought this kit in June and after six months it still works fine.  It fit my Kenmore washer as well as the original.  Washer is about 20 years old and all the original dogs had disintegrated by last summer.  I almost bought a replacement kit from Sears.  This one was about 1/3 the cost.  Although others seemed to be unhappy with the quality, this worked fine for me.  The parts appeared to fit properly and were not all that difficult to install.  However, since I live alone, my washer doesn't get the workout it would if I had a big family.  Whether it holds up as well as the original is yet to be determined.  As long as they used decent plastics, it should.  People often associate price with quality.  High quality can cost more, but more cost does not mean higher quality.  Since all my original dogs had fallen to pieces, I couldn't compare the new ones to the old.  But clearly, the old ones had become brittle with age.  You can't expect products today to last forever.  Consumers ultimately determine the quality of goods.  Since consumers today appear to be primarily price driven, any manufacturer's incentive to make a high quality, long lasting product is limited by what the consumer will pay and what his competitors are producing and charging.  Many times, I find consumers have little understanding of or appreciation for quality.  At least that's my conclusion when I see products that perform poorly and yet are clearly popular.
