"Just a note of appreciation for your product. I was almost to the point of giving up long distance rides on my Harley-Davidson Sportster due to the cramping of my throttle hand after short period of time. It got to the point where I felt it was dangerous and was not sure I could brake in a hurry if need be. I tried modifying my handlebars, using various gloves and... installing vibranators which helped some but not enough. I ordered your crampbuster and it made a world of difference. It is the single most improvement I have made to make my riding experience enjoyable again and it was very cost effective. Thank You!"
