Vornado 533 Compact Room Ventilator, 3-Blade Tabletop Fan, Black, 21 m³/min Airflow, 3-Speed Touch Control, Patented Vortex Technology

One of the reasons I bought this was because they reviews suggested they were well made and quiet. And it lived up to it.It is well made, and I would definitely recommend getting one of these over the plethora of cheap nasty room fans that saturate the UK market that laughably cost about the same. Despite it's small size this thing moves way more air than most, and the noise level is comparably lower. It doesn't vibrate itself to death.Being able to shift the same amount of air while being much smaller is of course much of an advantage to people without much room in their houses. Most people in the UK have fairly small houses and finding somewhere to store things is always an issue. Well finding somewhere to store this is much easier than a 16" pedestal fan!On it's first setting it is very quiet relative to the impressive amount of air it was still moving. And most importantly the noise is only that of the whooshing air, not the vibration of the motor or any other mechanics inside the fan.I say relative to the air it is moving tho, because even on it's lowest setting it's still moving a lot of air. And as such, it still makes a fair bit of noise. It's difficult to give comparables, closest thing I can think right now is louder than an idling PC/laptop, but quieter than a PC/laptop running at full speed (you know the noise I mean? when something is using all your CPU and the cooling fans kick in at top speed, right?).It's difficult to answer the question "is it quiet enough to sleep with", because that depends on each individual's tolerance for noise while drifting off; and how far away the fan is positioned from your ear. For me personally it's borderline, I probably can do but with difficulty, I relax more with it turned off.It's a shame there isn't an option to run it at half the speed of its lowest setting. Considering the build quality of the fan, I imagine this would be so close to silent that anybody could easily sleep with it. In the middle of summer if you have no quilts or PJs on, even the most gentlest of breezes is enough to make a huge difference. That air circulating slowly over your skin is much more effective at cooling you than static air. For this reason, on really hot summer nights I'd usually sleep with my USB fan on its lowest setting - much slower but quieter than this one. It's only extreme times when I'd feel the need to fire this bad boy up, even on its lowest setting.During the day it's different, sometimes you can have it pointing straight at you, sometimes circulating the air throughout your house as is its main intention. Also it's very big for a quick blast to cool you down if you've just finished doing something energetic for example.

The whole fan is perfect,sturdy base and frame wind switch for different power of wind,solid unit to take anywhere. IF THE UK PLUG COULD BE ON THE LEAD FOR UK CUSTOMERS BEFORE BUYING ALL THE BETTER FOR IT.

Please be aware that if buying this item through amazon it has an EU plug, and no adapter included. Amazon should include this information in the details.I bought my own adapter and product is working great so far.

I like the way you can feel the air moving anywhere in the room even if the fan is pointed elsewhere. It will not reduce the temperature of the room dramatically but will make you feel more comfortable.It’s lowest setting would be ideal as a bedroom fan as it is barely audible.

Superb design, don't hesitate. I've got the 660 and it's fantastic. I was really sceptical about spending so much on a fan and thought it wall sales faff. But I took the plunge and have not been disappointed. It seems the main patent is much deeper blades with a more powerful motor and a duct like intake rather like the design of a jet engine design. I've found the best use is simply pointing it up directly at the ceiling, you then feel a breeze anywhere in the room. It's awesome.

This did not come with an approproate plug.This is not suitable for use in the UK.

Arrived a week earlier than expected. Small compact, noisier than expected on the high setting, used in a 18' x 11' room on lowest setting and noticed an immediate effect, noise level good on this setting. Came with an English fitted adaptor. Invoice stated that if it came with a continental plug to contact them and they would send a free adaptor. So far very pleased with product and the company.

Bought as a gift, works well, arrived on time.Pity it didn't come with the adapter, had to buy separately
