So I bought this being rather excited about the quiet operation claims that it touts (oh what a rock star life I lead). On receiving the fan, the box is quite clear that it is indeed 25% quieter. It doesn't go quite as far as elucidating what it's quieter than, and that probably should have started some alarm bells ringing. For all I know it did, but I couldn't hear them over the steady drone of my new fan. On switching it on I found that whilst the blades moved pretty silently compared to a fan it was to replace, the body transmitted a steady and very annoying humming to any surface it was put on; the floor, a desk - even when placed on a padded surface. To be fair, there are 2 positions in which it is pretty quiet - when the fan housing is angled at about 35 degrees either up or down. Any other position is just annoying, especially as the noise it creates is arrhythmic - like a fat person snoring next to you; except in this case throwing small items at it and shouting 'shut-up' just makes you look mental. However in it's main task - that of moving small amounts of air around a room, it does the job.
