Edit 07/11/2013: 2 and a half years that I have this fan. It is being refreshed me :) it works like new and I turn it on every day at least 2 hours (even in winter !!). I recommend that more strongly. Price / more than satisfactory especially as the price decreased by 10 euros in 2 years :)
Edit 08/16/2014: More than 3 and a half years that I have the fan. The price has fallen sharply so I still recommend you more ... !!!
