My bedroom is small and it is on the weather side facing away, so that dammed the stale air. This I slept well and had often not waking up always feel an urgent need for oxygen. By Vornado these problems are solved and am therefore very pleased.
I must say though that I sleep with earplugs, because I live on a busy street where noisy even at night frequently occurring noise, for. Example by cars and mopeds. The Vornado itself is not very loud, but even at the lowest setting you can hear him at night very well.
Unlike the thing looks during the day when anyway noise can be heard from everywhere. I use it for airing my terrace, z. B. when grilled and spread smoke. The Vornado is finished very quickly.
Other applications, such as the circulation of heated air, I have not tried, but can not think well, in my experience, that works fine.
The device makes a high-quality impression, although the entire body is made of plastic, but then there are big differences. Everything you touch, whether body or switch, looks solid. The case is clear and safe, no matter whether erected vertically or horizontally.
I highly recommend this device to anyone, but would point out that it does not work silently. So: in the bedroom with me only with earplugs.
