Compared to the SPIN CYCLOP mirror is considerably larger and has a much better and faster overview. The installation with a screwdriver is accomplished quickly and easily. It's worth the holder half angle between the horizontal and the line of sight to be mounted to the eye, then the vertical and horizontal line of sight while driving can be adjusted easily and independently.
The selling of me CYCLOP mirror has a serious drawback: the provided screw to fasten the mirror in the horizontal axis is too long and can not be tight enough. As a result, the mirror does not hold its position but jumps to be readjusted at every pothole (or in the normal cycle track Berlin) from its position and needs. I have replaced the 8 mm M4 screw with a 6 mm screw and now this problem has been solved.
