VIVOSUN AeroWave D4, 4” Grow Tent Clip Fan with Detachable Hook, 3-Speed Strong & Quiet Airflow, Adjustable Airflow Angle for Hydroponics, Circulation & Cooling, Black, 2-Pack

Excellent little fans, move a good amount of air for size, a little bit noisy but not excessive. Great control of speed & direction of air, the magnetic base that allows for attachment to tent walls or on poles with clip is very useful. Overall very happy with them, used in a 75 x 150 x180cm tent.

Amazing little fan will be buying another soon

Convenient to position in multiple ways, get in awkward areas, lightweight, powerful, fairly quiet…

Excellent fans that move a good amount of airflow in my 2x4 tent. I havre one under canopy and above. They work great and are well worth the amount 👍😃

This fan is great the centre of the fan spins as well as the blade which gives a turbulent sort of push, Plants absolutely love it. I dangle mine from a light fitting and it kind of oscillates it’s self around.

Didn't even run for 24 hours and it's done. I bought 2, the 1 that still works is quite loud but does work. But honestly not worth even half what I paid. Very disappointed with these.

Much smaller than anticipated but good for the size

They work as they should but can be a bit noisy and not from the fan itself the front circular part also spins and when it does it clicks quite a lot but only on one I can't seem to figure out why

Lo compre por el bajo ruido que anuncian de 35db, pero emiten algo mas de ruido (39/40 decibelios en la velocidad 1) y en las otras 2 velocidades ya son demasiado ruidosos para mi. Por otro lado, las opciones de posicion y anclajes diferentes que tienen son excelentes los imanes tienen mucha fuerza y te dan la posiblidad de cambiar el tipo de anclaje en un segundo. Comenté al servicio de atencion al cliente el tema del exceso de sonoridad y me dieron una solucion inmediatamente, muy atentos y sinceramente un 10 para el servicio de vivosun. Recomendable el fabricante en mi opinión.

Top kleiner Ventilator. Könnte noch nen Tick leiser sein. Aber das ist jammern auf hohem Niveau 👍

for the VGrow it perfect and perform as it should ... for a really small tent or growbox i wish it could rotate and escalate to distribute more air

Para este produto eu avalio segundo aquele ditado: Tamanho não é documento! Ventilador usb mais potente que já vi em 3 anos como cultivador! As plantas adoraram! Possui um sistema onde a ventilação oscila, perfeito!

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.
