Product review (5 stars): Exact replacement.
Received the exact model as my old agitator. Includes the cam and paws. Did not come with the top dispenser, mounting bolt and washer, and cap/washer.

My original agitator on my Whirlpool WTW5521SQ0 had the tabs that held the cam in place melted/welded so I couldn't replace just the dogs. I assume this was done at the factory. Instead of buying replacement dogs for $1, I had to replace the entire agitator for $60. The new unit does not have the cam melted to the agitator. Someone else also mentioned the same problem.

I'm attaching images of the old and new cam for comparison.
