Unfortunately had the upper hinge half had dropped due to poor spot welding and the hinge pin was missing at all (would the packaging into the carton in any case be noticed!).
With a little hand work and two small M2 nuts and bolts but the lack could be corrected, because of poor final my moderate overall.
Smooth running and precise fit, for the man who's happy will have stainless steel and not black.
Due to the inconspicuous spot welds very delicate appearance but unfortunately prone to error, as already mentioned.
The size specification is misleading. Half the roof and turns the established Henkel, the window height is therefore only 30cm!
