It is sturdy and works well. We were happy with it, until the bike fell, just once, on the side it was installed, and of course the mirror shattered . While this may not be your fault, it will become so if you don’t sell spare mirrors. This would not be sustainable at all. I would of course not buy another one of these, nor recommend anyone to do so. I would buy one from another company that does sell spare mirrors separately. (Yes there is at least one!)
