I bought 2 pieces for my little ones in his 25m² nursery. The construction and the hanging was very simple. The lamp is also very robust. The package is surprisingly small and I thought the lights disappear at high ceiling, but constructed, the lamps look very funny, my son (17 months) jumps including quacking and rejoiced Supersize it. I screwed E14 LED 3,5Watt lamps and the room is very well aired by the two lamps.
