The rear view mirror is very good size and has a beautiful shape. I can not say anything about the functionality of the form, but I guess it will have its meaning. The adjustment of the mirror is also good. You can drag it a little harder by tightening the screw on the rotating wheel. Here but please be careful, because no matter how hard you put on this screw, you will be the mirror still easy to change in its position by hand.
Here you can expect far not forever fixed mirror and be reckoned with very very regular readjustment. This has the advantage that the mirror when you park the bike, sometimes can turn up purely to prevent it from others in the way. In addition, he is thereby understated, making it probably is also less attractive for thieves. :)
I too, like many others wondered at the beginning whether a bike mirror because not a bit would be freaky and unnecessary. I even read posts, this could be dangerous as distracting. I can only advise everyone: Try it! You will not want to miss it. Of course, one must not take to replace the shoulder view this mirror. Even here, there is a blind spot, which is the left side, a little behind you, depending on the mirror alignment. But a quick look in the mirror, a quick glance sideways are something completely different than having to always turn all the way back. In fact, this shoulder looking at cycling in my opinion a great danger.
Please note! When cycling you will buy this mirror probably like to look in the rearview mirror, and regularly, without real reason. Please try to keep it under. It's really very quickly that you lose yourself in the new rear-view mirrors and front brakes grade. Especially since everybody knows cars are a bit unpredictable ...
