Got it on day one, love it. Get it and you'll love it too. Agree it should've been standard. Slick as snot on a doorknob compared to the QS on the 2018 Ducati SuperSport S I had before the Rocket. It does need to be calibrated on installation and the dealer tool is needed. A few folk have had it improperly installed and it doesn't work properly.
You'll get the occasional lever warrior who didn't get it on their bike rambling about changing your own effing gears, but if you want to get max accel, your hands will never be as fast. And while a competent rider can clutchless upshift fairly quickly (but you still have to quickly back off/roll on for the change), manual rev matching on downshifts is a level of finesse that most don't get good enough to do well. That's why the QS tech started in race bikes, same reason they use sequential gearboxes in fast cars.
I initially optioned mine as I have osteoarthritis emerging in my hands, and constantly working the lever gets painful on a bad day, when all you want to do is enjoy the ride. Once I hit the twisties out of town, I rarely touch the clutch until I end up back in town. Pretty easy to get used to, and it's not like I ever forget to use the clutch to stop or start.
