at the moment, for £75 (as there is another tenner off offer at the moment) I think it is doing a good job, yes. Always find normal fans (even the swanky dyson one) just kick around the warm air, not cooling at all. But this is helping the room be less stuffy. Thought it might lower the temperature a little more, but all is all, it is giving a cool enough breeze, as opposed to just re circulating warm air!
I'd prefer air con but I'm not about to spend £400 to £500 when this does the job ok.
