First, I don't want bar end mirrors on my motorcycle.
That said, yes, the RE rear view mirrors almost always vibrate giving a fuzzy image of what is behind me.
At first, it bothered me but over time, I've gotten use to it.
If I see something behind me in the mirrors, that's good enough for me because over many years of riding I've learned to ALWAYS check to see if a lane is clear by rotating my head and looking.
If I'm not planning on changing lanes, I worry about what is in front of me, not if there is some cage or bike behind me.
