The installation is covered by the concealed hole plate easily, no additional holes and discreetly. The features are really well thought out and can be set up easily. The sun sensor is super - astonishingly accurate in the brightness measurement, so that the blind is not running on each small sunbeam down when you have it adjusted. A clock is not necessary to program just at the time where you want to have the upward or downward movement. I can only recommend.
