Note
Natural wind:
To help you experience the natural wind flow, the fan works at the minimum 500 rpm to maximum 1200rpm. The fan goes from one-two-three-four-three-two-one speed circularly, offering you the natural wind flow experience as you often feel when sitting on a lawn. The natural wind keeps changing its flow from low to high and high to low, and that's what this fan offers you.
You do not want to waste your time in switching off the fan again and again. That is why this OPOLAR fan comes with a timer that will automatically turn off the fan according to the set timer. The timer can be set 1-2-4-8 hours.

Great little fan. On low setting it is quiet enough that I can sleep with it running in my bedroom window.
We bought this to replace a small(ish) Vornado we've used for years as a vent, until it fell off the window sill. We selected this one for size and "uprightness" to sit on the narrow ledge. It was also inexpensive enough that if it didn't work it would be OK. But despite the small DC power supply, it moves a decent amount of air, and is relatively quiet. The DC power also gets you more speeds/modes and a timer because, digital controls. I can't speak for durability yet, but for meeting initial requirements it's solid.
I have been buying this brand for a while now and have been satisfied every time. I have multiples of they're four inch fans I've purchased their mini 500 watt heater which is excellent to. I like this 8in fan cuz it's constant big wind at variable speeds low noise perfect for desk work for blowing in your face at night I just love opolar brand I've had the 3 speed 4-inch fans on non-stop for a year no noise and start right back up and sound the same as they did when I first got after cleaning no motor strain. When you find something that works and you like it you stick with it!
We use this on the deck, when we don't want to lug out a plug-in floor fan. Not as strong, of course, but much more portable. A good buy for us. But the logistics is a bit slow
This product is just what it is stated on the website: small, quiet and lightweight. I've been using this fan for a week now. The 5 speeds is a real good feature. The 1st & 2nd speeds are pretty quiet. I've been using the fan to circulate the air in my bedroom at night thus the 1st speed has been extremely benefical. The timer is the second best feature. The 4 hour tiem slot works best for me, auto-shut off just around 330AM - just when the air just cool enough to not be cold to sleep. No more getting up in the night to turn off. The 3rd feature is more physical in the I really like the BOX shape; it fits perfectly on my window sill. The 4th best feature is the USB plug as I can now travel whereever I go, use an AC/DC adaptor or my laptop. This fan a is real winner in the peace making sound department.
