I am going to try to keep this review short. A difficult task, as these fans are simply spectacular!So let's get right to the heart of the matter. If you have any kind of an indoor garden, and you want to massively improve the health and productivity of your garden, these are your fans. Only a FEW HOURS after installing these fans, I could see the difference in my plants. And within a few days, the results were very obvious and very exciting.Installing the fans could not possibly be simpler. The clamps are made to attach to poles or a frame of some kind, presumably in a grow tent. However, I do not own a grow tent but still very much wanted to employ these marvelous fans after reading all about them. So what I did was to make some poles of my own using bricks and mop handles. Most any heavy object could be used as a base, as long as it can hold a pole up vertically, such as another version I made using bricks and 3/4" PVC pipe about 5 feet in length. And since these genuinely awesome fans only weigh 2 pounds each (yes!), any pole or frame that can support 2 pounds will hold these fans beautifully. It literally takes seconds to put in a screw, adjust the tilt and clamp the fan to a frame. Installation done.These fans are also SUPER QUIET. Amazingly so! I have never used any kind of fan in any kind of application that was as quiet as these fans are. You have to be close by to tell if they are running by the sound. Which is a beautiful thing.These things move some serious air! I am only using speed setting number 2 out of 5, and I would never need to increase that speed, at least not from a close distance. And that's another wonderful feature. Whatever your horticultural setup is, and just about whatever your distance requirements are, these fans DELIVER in the air flow department. And the fan blades, the housing, indeed everything about the shape and design contributes to stellar air flow. The best I have EVER seen.It goes on and on. They have a metal gear to control the oscillation, not a plastic one. This will prevent the oscillation function from failing for a long time, if ever. The motors are "EC" motors. I didn't know what that really meant, so I had to look it up. There's quite a lot to it, but suffice to say that EC motor technology combines the best of AC and DC motors, AND results in lower operating costs and extended service life. What's not to love there?Finally, I would like to add that I contacted the company for even more details, because I like these fans so much, and wanted to know everything about them. Here is some valuable information I took away from that correspondence:These fans are designed from a special plastic that is not prone to breakdown from being near high intensity lighting, such as LED lights or other high powered lights often used in horticulture. And they are temperature resistant as well. I had to message them more than once to get all of the details, but there is in fact no minimum distance requirement for these fans to be a certain distance away from an LED light, as long as the fans aren't actually touching the light bulbs! That's outrageously awesome! Try hanging any fan made out of regular plastic only a few inches away from a high powered light for months and see what kind of results you get!The bottom line is that these fans are, in every way, worth every penny you pay for them. Yes, they are more expensive than some other fans, but the value and performance for the money are in my opinion absolutely off the charts! I love these fans so much I should apply for a public relations job with VivoSun! No kidding! I just cannot help but gush about them. If there is one single thing besides a high quality light which will catapult your indoor gardens into the stratosphere, it is installing a pair of fans such as these. You WILL SEE RESULTS IMMEDIATELY!

Stopped working after 3 days!!!

As with all vivosun products, These fans are awesome! I really like the "natural wind" setting. Very quiet too.. My only complaint is that the 2 pack doesn't include the Vivosun USB splitter which is required to use both at the same time.

As described, fast shipping and great product!Quiet , easy clamp on design, sleek and pushing lots of air flow.

Barely moves air and cords aren’t long enough to reach outside my greenhouse
