I know there is a lot of BS about "Chinese" crap. But don't blame the manufacturer, blame the company that contracts the manufacturer for not doing propper quality control.
I just bought 2 Spicer (Dana) u joints "Made in the USA" printed right on the box.
3 of the caps measured 1.078+/-
1 of the caps measured 1.06 something
the box was factory sealed!
All comes down to quality control.
I have never seen a temp sender be defective that wasn't damaged.
