not for window Exterior blind

The product was geliefet as described. What I had nowhere exquisite advance is that you can not install it if before the balcony door a Exterior blind is attached. For me, the space between the balcony door and Exterior blind is not big enough. We are now attached to the outer shade and must always remove it if we let down the blind.
In addition, the individual slats at the bottom are provided with a small Plasikleiste, in which a piece of metal is to complain the fins - this is me now fell out several times. It is easy reinzustecken again, but it annoys me.
The quality of the "substance" I consider very good, because he is very strong and therefore certainly durable. Apart from the idiosyncratic metal parts I can not fault the quality.
