Got mine nearly a week plus ago.. And it works great! Really need to get used to it especially on how hard you lock the knob.
Too loose and it won't hold the throttle, too tight and you can't turn the cruise to lock.
Great stuff.. But i recommend once you have found your locking sweet spot leave it there. Once you remove it, you're back to square one readjusting it again. Oh by the way, i'm located in Asia, Singapore. Asked a friend to help me purchase this.
