I manufacture and sell a bicycle eyeglass and helmet visor mirror. Most sales come from my www.safetyspotmirror.com website, and I also sell through Amazon.com. I currently have 11 dealers, from California to Singapore. A purchaser from South Dakota gave a good, description: "I have been using Safety Sport Mirrors for about ten years. They are the best by far!" Other mirrors are still in service after 25 years use.
