Very easy to use... looks good.... works well with the Rocket. Since the Rocket is somewhat heavy and is very powerful you don't need to do a whole lot of adjusting as you ride. I have the heavy duty (recommended, especially if you wear gloves alot) and I like it....
i'm not sucking up here, i know that tom has tried many different setup to make long trips easier on the hand. so if he's finally found one that he likes, then i'm sure just about anyone would be happy with it.
I also have the Heavy Duty Throttlemeister as well as a plastic device called a Throttle Rocker. I have the older one that just loops onto the throttle and not the new one with the veclro. Go to http://crampbuster.com/ to get the old version which is far superior.
The Throttlemeister is good for the long flat straight aways while the plasic device is great for letting the wrist relax a bit when needed.
I have a Throttle Rocker that I used to use on my Speed Triple. I put it on the Rocket III and while wearing some gloves I was able to almost rocket the Rocket out from underneath me. I took that baby off and it hangs on my garage wall to this day.
