Got mine today. I don't really hear anything metallic. They do, however, sound and feel exactly like the silent reds that I just removed from a filco TKL b/c they were the worst MX switch I had ever used. So... I'll be selling mine.
I don't think lube would help. I lubed every goddamn inch of my reds and it did nothing. The springs are just too tight on the stems and they rub (even with lube) causing some serious scritchy scratch.
It's unfortunate, but "c'est la vie."
