Not bad but still only four stars

The technique of the blind conviction. The attachment is not a problem using the supplied illustrated manual. But I recommend everyone to the window frame not only mount the blind, but also to use in any case the Pats for bonding. The Rollo holds simply better.

Now I come to quality. Here I realized that the fabric pieces are poorly laid out. This ever dissolves a thread and entangled during winding and unwinding the roller mechanism. This can lead to unclean coils. You can prevent this but, by burning down the protruding threads with a lighter. But be careful, otherwise the whole roll is burnt !!!! This I can not award full marks.

In other reviews is reported that the blind wound obliquely. The fact is sometimes true. As a rule, but this is not the blind, but the fact that the sash is not installed horizontally. Thus, the blind is not exactly horizontal on the wing. But is not a problem as window sashes can be adjusted.
