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.

Perfect for a small grow tent. I got a pair. The magnetic placement is a game changer. Can't recommend strongly enough. Quality kit. But, get a long usb to usb cable - i, i think got either a 3m or 5m, so I have plenty of leeway. They don't come with the fan, so make sure to order those too. Standard USB cable you'd plug into your laptop, but with the same connection at both ends. Very many have multi ending connections, i.e male to female, male to usb-c etc. So be careful about this. I hope this is clear. https://www.amazon.co.uk/dp/B0080HAYLK?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1

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

Amazing little fan will be buying another soon

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 👍😃

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

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.
