VIVOSUNAeroWave D4, 4” Grow Tent Clip Fan with Detachable Hook, 3-Speed Strong & Quiet Airflow, Adjustable Airflow Angle for Hydroponics, Circulation & Cooling, White, 1-Pack

I just received this fan in the mail today 2 days early and nicely packaged so that’s always a good start. I bought this fan for the purpose of putting it in my vegetable indoor grow tent for circulation because it has sooo many options to how you want to put it either set on the bottom on it’s feet, clipped to the poles of the tent(which has a great sturdy clamp so no slipping down at all!!!) in which you can adjust it up or down which is great, you can hang it from the top poles by the top of the fan which has a loop for any type of string or anything you have to tie it with which is a great option, and it even has a strong magnet to attach it to anywhere on the walls! 😱 which is awesome! The metal plate to put on the outside of the wall to magnetize to isn’t included but it’s cheap to get if that’s how you want to use it. So it’s absolutely perfect for what I needed it for and it has 3 settings of low medium and high and is very powerful on high for such a small fan especially and it’s so quiet I didn’t even realize it was on at first honestly! But as I was looking around I realized that I can use it on my end table next to my bed for a nice cool breeze or in my living room while watching tv for good circulation I mean it’s uses are endless and it’s a nice design so it’s nice to have out too. So I’m definitely going to need more of these even for when I go camping for in the tent! So I will absolutely recommend this product to my friends and family etc and it’s definitely worthy of 5 stars to me!

I don’t usually write reviews unless something really impresses me — and these fans absolutely do. I now own six of them and use them daily in my garden setup. They’re incredibly quiet, even at the highest speed, and the airflow is surprisingly strong and customizable. The fans are very well made, durable, and are nice and small so fit in my greenhouses perfectly.The adjustable hook is genius — I can direct airflow exactly where I need it. Between the multiple mounting options and the angle adjustments, I’ve been able to set them up in tight spots, on poles, and even in grow tent corners. They’ve made a huge difference in temperature control and airflow for my plants.The one-touch operation is simple, and I love that it remembers the last speed setting even after a power interruption. If you’re looking for a reliable, whisper-quiet fan that punches well above its size, this is the one. I can’t recommend it highly enough.

Those who say this blows hardly any air are plain wrong. First this is not a 6” so quit expecting it too. I have two 6” portable fans in a 4’ x 2’ so there you go. With this I can take the 6” at top of tent above light and replace with this. This blows a surprising amount of air quietly on 3 speeds adjustable direction. I prefer usb as I have 2 tents and take all precautions to keep wattage use down. Not partial to fires. What I am using these for is at the very top of my tents on the side where my bottom intake is. I then blow towards my carbon filter at opposite top to remove hot air at top of tent. You have 3 speeds then to adjust for heat but the higher speed might be overkill. Cool mounting options. Not UL rated but is really well built. I think they are well worth the price and I have two. Will be getting another just to have for other usesl I have a usb power brick and these would be the ticket for a concert.

I have a smaller tent, so these 4 inch fans work perfectly in my setup. On the top speed setting they get a bit noisy, I keep them on the middle setting.I do appreciate that they work well with timers. I’ve tried fans that don’t remember the setting after being turned off and on, these fans have zero issue with that.The rotating cover is pretty cool, and moves air around in a wider space. However, if you have the fan pointed down, the rotating cover rattles.The pole clips are a helpful addition, I did have to replace the washer on one because the screw would just keep turning.The fans are also very lightweight; I have one magneted to a screen with a small metal plate on the other side.

Very powerful and efficient fan, has 3 speeds and connects via usb a which is nice. If you wanna connect to a regular outlet make sure you have a power brick adapter. Has kept my plants healthy and happy for months and the clip holds up very well

Why did you pick this product vs others?:I bought this because I love my VIVOSUN humidifier and assumed these grow tent fans would also be high quality (and for the price - each little fan is 15 dollars) - I have now had them for about 40 days and BOTH fans have failed. I have a third one I bought in March that's still working, however, the oscillating feature now squeaks and its rusty. Has a one year warranty, reached out, if they respond and honor it I will update the review.

I had to tie the fan in position because the clip is not strong enough to hold it up so it just falls back down. It’s not silent but it’s pretty quiet. It has 3 speeds you can adjust it with.

Perfect for my micro cloner tent.I wouldn’t run these in anything larger than a short 2x2 or 2x3Great for keeping air flowing around your led panel.I would recommend a main fan for the plants to gain strength.Bottom line I like them, I wish they sold a usb hub with them so you don’t have to use multiple charging blocks.Also they use an abec7 bearing on the fan shroud, you will notice it when you clean it.Abec7 use to be top of the line bearings when I was a kid skateboarding.
