The replacement of the light-emitting material with a saving bulb I like that, but with me fits only one light source 8W instead of pre-sighted lights in the unit.
The construction went smoothly with the supplied dowels. Only the building is connected to something friemeln.
The complete unit consists of a thin material which makes it easily deformed. For me, this reduces somewhat the Valence Wahnehmung.
Otherwise, for the price a good device.
