I saw a comment, by a Chinese company I think, that said the very best, and the very worst products are made in China.
The trick is finding the right manufacturer !
Where possible I use local manufacturers ( South Africa in my case ) for assembly, engineered parts and pcbs, but the LEDs for example all come from China now, whoever I buy them from, and they are ten times cheaper when I import them.
Luckily I have found a good supplier ( so far, so good ) although the latest batch have the short lead, and the flat on the body, denoting the anode !
When asked about it, the supplier wrote, " we call them the reverse polarity type " with no further explanation ??
