Somehow this sun visor is not exactly brilliant. Sure, she sits again on the lens makes them what they want, but by the application mechanism which is sometimes not so easy. Normally you screwed yes sun visors on the lens. Here the diaphragm is clamped onto the lens by means of two small pushbuttons. Unfortunately, this is somewhat tricky because iris somehow sometimes does not seem to fit. Wedges and then tilts and sometimes makes sitting appears and then drops again. Sits once it is rather shaky ... she holds, but is simply rickety. For me, a pure misconstruction. And we are talking about a piece of plastic which more than 25, - costs. As one might have expected more.
Two stars for the good will, but I recommend clearly looking for Altnerativen!
