@WYtreasure , I heard back from Temco this morning, and they say that their products are made in China in order to keep costs down.
I do not appreciate the American flag theme, and language about their company being an "American team" on the front page of their website--- it's clearly intended to mislead people like me and you into believing that these products are American made. Temco doesn't state anywhere online, on their products, or in their paperwork what the country of origin is. They specifically ignore questions about this on their Amazon store (while answering other unrelated questions).
