Der Spiegel has thrilled me - a clear image with large field of vision. The reduction I already knew from other rear-view mirrors and was used to. The adjustment is good, the mirror does not not moved by itself, even on bumpy trails. But then the big disappointment. The holder of mirror Nr. 1 was already broken after a week. The entire holder on the handlebar is made of plastic and the lower half-ring are obviously under stress quickly up the ghost. In mirror no. 2 the holder was already in half during assembly. That is why only one point. A holder which is obviously intended for a loose assembly, missed its meaning.
