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

Works well with the VIVOSUN controller! Love it may purchase another!

Works great

It looks really cheap but it gets the job done. I leave it in my small greenhouse. It keeps the air flowing but I can be loud even the weakest setting.

Great powerful quiet

I love this little fan. It clips on to the frame well and it’s easy to install and adjust. It’s been running 24/7 for a couple months now and I haven’t had any issues. The quality is great, especially for the price. I definitely recommend.

The media could not be loaded. I really like this little fan! Has several different speed options and pushing air pretty well in a grow tent. I love that it has a magnetic option if you don’t have the ability to hang/clip it. I do wish the clip was slightly larger as it doesn’t quite fit around the poles in my grow tent. Other than that, no issues with humidity (mine stays between 70-90% humidity) or with running for hours on end.

It blows but barely. It is so small, it moves minimal air. Go for the big one.

Here is the disappointment you will have. Picture shows two fans sounds great dosnt it. Well guess what you only get one fan. The picture of this misleads you to think your getting a great deal your not only getting one fan with a USB power source with no block. Also the cable is not long so don't count on that. Sure it's a good fan for what it is but being mislead into thinking you are getting two is enough two make sure that you will buy another fan next time.
