To say it right away: For this luminaire is ideal. It is not really ugly; I would grow with me in the kitchen (but then rather under a cabinet where the thing is not necessarily a constant eye has).
The switch is also one of the two lights, which I use, as with the other reviewers kaputtgegangen- also. For me it does not matter because I run the lights at a centrally switched outlet.
But an on / off switch is obviously such an important component, that I at least have to deduct a star for it in the overall assessment.
