I like these grips and think they are a fair value. The throttle boss does give the ability to stretch the hand out without releasing the grip. The issue I had (as stated in other reviews) is the little defects from the production process. I could not get the throttle to snap back after installation and finally figured out some glue and plastic inside at the end of the grip was the culprit. After scraping and reaming with a screwdriver and file; problem solved. I'm sure I could have returned/exchanged them but that would have been more trouble.
