Since I wanted to have a small inconspicuous mirror, I opted for this model. With my bike (MTB) I had to mount the mirror so that it shows up front diagonally in order to see something can, below it is hidden from my hand. Unfortunately, this position has the disadvantage that the mirror I ever accidentally disguise - when getting on and off and even when thoughtless hands Enter. After that, the mirror must be aligned each pretty much back as it provides only a small field of view of its small size and curvature, and only a few degrees of tilt decide whether I the heavens, the road or can actually see the traffic behind me. This is probably in principle and not to blame the mirror, but it may help to bear in mind before buying it.
