Perhaps early renditions of them were bad, or maybe there are more than one manufacturer. The pass side one I bought from PG, which is what year one sells, has very nice chrome, feels sturdy, and the glass pivot is nice and tight to the point where I couldnt possibly see why it would loosen over time.. it’s not the kind of thing that gets adjusted often. I think it will be fine but I suppose time will tell.
all that said too, I’ve had many early oem factory ones get loose and crappy over time too. The last set on my dart sport 360 car weren’t great…
Just posting this so when people search these mirrors the can read this. Perhaps it will help their decision making..
