I had an airblade fan. Terrible. My wife smokes and the fan clogged up with a mixture of nicotine and dust. There is no filter to stop the dust getting in. I had to strip it down (including motor) sever times just to get it to push any air through. Lasted 2 years. Dyson customer service were unresponsive.I don't get the love in with Dyson mind. Had 2 now, 1st model, and one from about 3 years back. 1st was average at best. 2nd, that would have retailed at nigh on 500 notes (I got cheap), was f***ing abysmal. My 80 quid Electrolux was far better. C unt also used to fall over, if you pulled it in anything other than a perfect straight line.
