Delivery very fast, packaging is not quite as good, strongly pressed cardboard box but without prejudice transformer. Operate 6 LED lamps a 3 Watt 18 Watt total so without any problems. Slight delay in turn, hardly perception of warmth of the transformer. Top processed and it also causes no Noise in consumer electronics. (Surround sound system HARMAN KARDON). I'm very satisfied, highly recommended. Despite depressed box 5 Stars.
