The assembly is very easy, the device looks visually very good. The fan noise is overall quite pleasant compared to other devices that I've heard.
But unfortunately, the Rowenta VU 6520 Eole has given a clearly audible rattling noise of in the panning mode to perhaps 15 to 20 minutes duration. In the normal state of mode it was gone as soon as the pan is turned back on, it was there again. It may be an isolated incident, I can not judge. A great pity, or he was really great, but volume and noise were the most important criteria for us and he is ultimately unfortunately failed.
