Installed them on my 2019 F3L. They are solid. The aftermarket rests I have seen are flimsy in comparison. You do have to give up the heated passenger handgrips - not a problem here in Southern California. The armrests themselves are a bit slippery, so I put some transparent anti-slip tape on them. My GF is very happy with the setup.
Passenger heated grips work fine on my 2021!
I have installed the BRP arm rests on my 2021 S2S they are nice and as stated above solid with little adjustment, but there are after market plates you can get from Spyderpops, slingmods and the others that will give you a bit more height adjustment and forward/aft adjustment. The stock height was to low for my wife and she is pretty short, the plates put the armrest in just the right place for her. They do swing (pivot) out about 1 1/2" to 2" for egress off the seat and there is a spot on the forward bottom of each one to mount a four bolt ram mount ball for drink holder/phone/gopro or what ever. I mounted a 1" ball mount and 2" extension swivel and cup holder for the wife.
Also they do not replace the grab bar, when mounted they sit over the grab bar and mount with a hook in back and a bolt in the front. You replace the plastic panel around the grab bar with the provided half panel. Takes 10 minutes or so to install both arms.

The arm rests are a nice addition for me, my passenger (wife) has a tendency to fall asleep on long rides even on my superglide she would fall asleep and I had to hold her against the back rest. On the spyder with armrest no issues. She can fall asleep and still be secure without me holding her on/in.
The first owner of my bike put a seat belt in for his wife, because she would get on and fall asleep on him!! It was the first thing to be taken off when I rolled it home!!hyea:
That's an idea (seat belt), but we haven't had a chance for a long ride yet weather being what is is here in Nevada, but I will keep that in mind if the time comes. She should be good with just the arm rest and I am considering the driver back rest so she would be boxed in.:2thumbs:
