As I replied in the reddit thread, Fluke manufacturing is in the US and China. Most "Made in the USA" products now are "Made in the US with US and non US components" indication -

Basically a fancy way of saying the product was Assembled in the US.
The C versions of Fluke, as 289C, 87VC, 117C and others as they exclusive models (13B, 15B, 17B, 18B that now are in their MAX denomination, after the B+ one) are Made in China and in the US. Those models don't have warranty outside of Mainland China and can be sold or given support outside of Mainland China.
The difference between the C suffix equipment and the non C equipment in terms of functions, construction or components used are exactly none.
They are Fluke, with Fluke quality, just assembled in different countries. So as lots of other products, manufactured by international brands in China, that we use every single day and have quality I don't understand the pickle of not being USA made.
Probably you don't want to support China and their practices and I understand that, but in a global world as this one, I'm sure every product have stuff from China even if it is the plastic (pellets were made in a factory in China) or the rare earths (mined in China).
