I’ve mounted now more than ten of these lamps in our home. The proportions are beautiful and the adjustment mechanism works well and they overall look and work great.
The attachment with the two threaded screws could be replaced by a large thread on the inside of the housing so that the whole lamp would simply be screwed on the base. This is because the current attachment mechanism is quite fiddly. Also the quality of the threaded screws is not very good, they are too soft so the hex bit easily slips and the paint scratches easily. So I bought a bunch of m3/15mm screws and painted them once attached.
Additionally, it’s 2025 so I don’t want to see luster terminals anymore but you get a bunch of Wago 221 and use those instead, there is easily enough room to do that. I would be happy to pay bit more if these issues are fixed.
