Product review (5 stars): Faster delivery, less expensive than the traditional means of aquisition. Exact same part/packaging however
The dogbones in my washing machine finally gave up on me and the agitator started free spinning (meaning clothes weren't actually getting washed).  I originally purchased this machine from Sears so of course thought that would be the right place to find replacement parts.  Did the research, found the part numbers and started the process of ordering their. Turns out theirs is more than twice the cost of this, required a week or more to get to my local sears, and was stated up front that it was a non-returnable part (in the event I accidentally ordered the wrong one).

Well, that convinced me to come here and find the exact same part (literally the same manufacturer packing/bag) for less than half, free shipping, and two day delivery.  Going without clean clothes for more than a week wasn't sitting well with the rest of the family...

Installation took less than 10 minutes (I purchased a replacement Agitator Bolt as well, Whirlpool part # 358237) as I just pulled off the cap (pried it off at the notch with a pocket knife), unbolted the old system, pulled the agitator off, wiped the inside down with a damp washcloth (get rid of 15 years of "stuff"), push the new cam down and put the dogs on it, then the top and re-assembled.  Literally took as long to type as to do.
