I'm not clear on what advantage these have over other mirror options. They look to me like something put together using old RAM ball parts. Stock mirrors worked fine for me, but the turbulence was a bit more than I liked, so I just installed the Aprilia version - have not tried the bike yet. And $120 sounds a bit pricey to me.
One disadvantage you did not mention is passers by can fiddle with the knob, loosening the mirror and changing its position - or worse, stealing the mirror (though why would anyone steal a mirror?).
I've been noticing these adventure mirror threads the past few days and, as I try to apply my tiny brain to it, I can see the value in having a mirror that's designed to move on impact without bending the stalks, or mounting point, etc. So if you drop your bike or it hits something, the ram arm just gets forced to rotate a bit, no damage done. Or if you're on a trail or on your own, you can just remove the mirrors.

or like you said fiddle with the position. And If they knew how much they cost that might make it worth taking.
Luckily for me I rarely leave my bike unatended. For others in this situation may not be as lucky.
I've lived in apartments for most of my time riding motorcycles. And I've owned RAM mount stuff. There's a small chance that people will come look at your bike closely, and even smaller that someone will mess with it. I mean, technically, someone could yoink our stock mirrors if they wanted.
But for extra security, I've done two things to help deter.
1) Ram makes a lockable, sort of "keyed" tensioner. This is what I currently have on my bike. I originally used it for something that was semi-permanent. Something I would keep on most of the time for commuting, but maybe switch out if I wanted to go for a tour. https://www.rammount.com/part/RAP-S-KNOB3U
2) When I had something permanent (I have a GPS and Security Card holder I want available all the time as I need to show my security card to get through the gate for my job), I ended up taking the threaded knob off entirely and just going to a local hardware store and getting two nuts that fit the bolt thread. First one tightened it down, the second one went on top with threadlocker to sort of "lock" in the first nut. Worked like a charm.
