I have used the Big Boy Pedal Extender on several of my buggy builds, and with great success. My personal buggy was finished in June 2014 and has the Big Boy Pedal Extender with the double-supported roller on it, and it currently has over 43,000 miles on it, covering the North American Continent 3 times from the Atlantic to the Pacific, including Alaska. Very good quality items and workmanship.
