Product review (5 stars): Did just what it's supposed to.
The part arrived on time and as promised: I replaced it that day.  It's a plastic bracket that connects three pairs of wires safely.  (Similar to a wiring-harness; not rocket-science.)

Buying this from Amazon was MUCH better than buying from Sears Parts Direct.  Sears tried to over-charge me for the part, tried to keep me on the phone as long as possible, offered very limited "discounts" when I pointed them to better prices on the web, and tried to use "scare-tactics" to keep me from buying the same part anywhere else.  Sears insisted on charging me $5 a piece for the two screws that attach the block to the dryer, even though the old screws I had were just fine.  Sears also tried to cross-sell me several expensive things, such as a specialized lint-filter-brush.  If it were just me, I might think it was funny, but sometimes scare-tactics like those work on old people, which makes it not funny at all.

Amazon (and the third-party vendor) offered a square deal on the right part.  I appreciate that.
