Product review (5 stars): Mine Worked with Minor Modifications
Yes, it is assembled in Mexico.
As with many replacement parts, in my application (older Whirlpool), I had to cut off old wiring terminals and install some new ones (supplied).
Yes, the wiring instructions could use improvement.

Other than the above concerns, it was completely bolt-in and relatively painless to install.

The build might be slightly leaner than my old 25 year old motor, but I DO NOT hear the increased noise other reviewers indicate.

With Amazon Prime 2-day shipping I was up and running pretty quickly.
