Bicycle Rearview Mirror with 3-Mode Red LED Light (2 x AG13)

Pros: The rearview mirror on the bike is 'must have' item cause modern cars with their silent motors creep as a ghost and threaten your feeble life. This item makes the life better. It's body and holder and mirror itself are made of plastic. Mirror has a convex plastic glass, so the range of vision is very wide. It is designed to mount it to the handle bar in the manner the mirror is outside the bar. But as I sometimes meet columns, fences and walls with the sides of my handle bar, I mounted it on the left side under the bar in the manner the mirror is inside the bar edges, so it's protected even if the bike (and it's clumsy owner) meets the pavement. It was very easy to mount it. All you need is to loosen the bolt, insert the the plastic anchor inside the handle bar and then tighten the bolt. It fits my Jamis bike perfectly

Cons: the convex glass makes objects in the mirror very small, and after driving the car it's very hard to estimate the distance between your bicycle and the truck behind you, to calculate the approach speed of it and even to read the line it goes. Object in the mirror are degraded and only headlights help to read the traffic information. But this information is enough to keep the cyclist from changing the line, making the turn or other dangerous maneuver. The item came with the discharged batteries, but they are very cheap here. And I don't really understand the purpose of red light in front of the bike. Here in Russia we need to use white light in front and red on the tail according to regulations.

Other: I am rather happy with this product, cause it's small enough not to clutter up and overload the bike and functional enough to help me on the road
