For those of you who are not happy with the quality of the TNT F1 mirrors, we offer these high quality mirrors by FAR Italy. They sell individually either for left or for right. Set includes reduction pieces to fit M10 threads into M8 holes. Thread is some 3cm long, it's best to check whether this will work with your scooter (there may be some problems with Speedfight and Area 51). There also is a version with a carbon style body that comes with an extra joint in the connecting arm, hence adjusting it to your own field of vision.
