Unfortunately I can not recommend this bike mirror. Good thing about it is the firm but flexible gooseneck. The pronounced due praise. Also good is the adjustability of the mirror in the holder. Without these two features in this product I would receive only one star. Because of the mirror itself is really much too small and reduced to the extent that he is actually banned as too dangerous. Sometimes I wonder why producers with really good innovative ideas completely spoil their product back by a peculiarity. Maybe it's good that you recognize in the mirror anyway hardly anything, otherwise it would be hard accident hazard. Namely, when the mirror anything similar like a car thinks quite far back perhaps 500 m far away to recognize a car, then this car is already directly behind and is already to overtake. I do not in any case - the car is really still farther away, you can not see it absolutely. So please, dear Manufacturer: Put on your great gooseneck reasonable levels, large enough and not having this insane reduction. Indeed, it is the howl that you simply can not buy a reasonable rear-view mirror for the bike and the best of intentions.
