Dave, I can understand your disappointment as I too have seen a quality down grade on MSC/Enco "import" products here in the last couple years.
It seems a given product, like a vise, that was produced in Taiwan at a reasonable quality level has been resourced to the mainland or India.
The result is a product that is "pictured" the same, but on close inspection, ain't even close. Even the quality of the metal has suffered, and that is not apparent to the eye, until it breaks and the dirt occlusions are exposed, only then can the inferiority be seen.
