To me they are like a steering damper. I bought mine used (great shape) to try and see if it was a gimmick. Turned out I love them and now have to have them on any bike from now on. Hard to describe, just makes standing control eaiser for me, and no shifter/brake issues even with bulky boots.
Maintanence can be done with the main part (post) still on the bike. A 17mm nyloc nut holds the peg part on and comes off easy.
It's really hard to remember you even have them on your bike. Until you ride a bike that does not have them.
Like Glen I have them on my 300 and 510.
When you first install pack them with lots of grease and assemble carefully. I have not had any problems.
When I'm on my Trials I do miss them. Hmmm I should see how much work it would be to put a set on it too.
