I have a pair on mine. Don't expect CRG quality, but Cycle Gear has awesome customer service. Snug down everything before you start riding or parts might fly off. The first pair I had vibrated like crazy, then the right side mirror glass flew off when I was on an on-ramp. They shipped a new set, no questions asked.
Quality is just okay, visibility is excellent, price is awesome. They also come with bar-end adapters so you don't have to shell out extra money for those. You might feel more vibes through the bars, though, since the mirrors aren't terribly heavy.
