Was a little smaller than I had imagined but only meant it fit more neatly into a corner, hardly takes up any room at all. The fan itself is slightly weak but cools my small room perfectly adequately (about 5m square, maybe slightly less) though so far I've tended to leave on the highest setting when I'm in the room, though the others I guess would be fine to keep the room cool for when I get back in. I get the impression it would struggle keeping a larger room cool though. The sleep mode, as I have read from other peoples comments is bizarre, randomly changing speeds, very odd, and no doubt would disrupt sleep, ironically. Having said that the fan is pretty quiet and is quickly forgotten about, it's the intermittency of the sleep mode that would getting annoying. The timer is pretty simple and functional but could do with more than the 1/2/4 hour options but that isn't really a problem. Oscillation works fine. No technical problems with the machine what so ever. As for the ioniser function I can't really comment, I'd read it gets rid of floating dust etc. so I decided to buy something with this function as can get irritated by dust etc (slight allergies) maybe it's something I may notice more in time but immediately there seems to be little impact to me.
Anyway, all in all a good product, suits me fine.
