Am satisfied with the part to have or to "diagonally left behind" to check for left-turning operations to traffic of the Überholverkehr in mind. Because the product is so small and right on the hanger sits (the belt), it slips virtually impossible by the vibrations when driving. So you can see if a car is coming, yes or no, details of which you do not need indeed to be recognized. Because of the handlebar position somewhere between the handlebars so you can not really look "behind", but only laid back, because even the sight of the mirror blocked directly back. But to hedge the intention to turn it enough just now, since the mirror has a "wide angle effect".
