I had only a minor issue with the riser extensions that i bought from them. They shipped with the wrong size bolts. When I e-mailed Scootworks about it, they replied within a day to say that all of the recent runs of the risers had the incorrect bolts. They pulled all of them to replace the bolts, and shipped me replacement bolts free of charge, and I had them in hand a day later.
