TN TONNY Dual Head Clip Car/Home Fan, 12V/110V 4 Inches Electric Clip on Fan, 360° Rotatable Adjustable Cooling Air Fan with Stepless Speed Regulation and Brushless Motor for Vehicle or Home

This is a nice double fan setup. I've had it running 24hrs a day for 2 days with no issues. It is not the most quiet fan. If your looking to be super stealth I would get something else. For my setup, noise is not a concern so it's fine for me. Speed adjustment works good. Moves a lot of air.

Best fan for your grow room or tent, The clip is really tight so it stays were you put it , the 2 fan design letting each Independently moving is brilliant... Order 3 or them on sale for 12.99 .. 2 in my 20x10 flower room & 1 in the 4x4 veg tent... Working marvelously 👍😂

I was immediately very impressed by how quiet this fan is. I bought it for my work-at-home work station. My wife promptly stole it from me. So I ordered another one.The fan is very quiet, especially at lower speeds. But even at top speed, it's still fairly quiet.The two fans run at essentially the same speed, but they are not synchronized, so sometimes there is a mild "interference beats" effect. I hardly ever notice that, but when it happens, I just nudge the speed a bit and it goes away.The hardware is very robust. The clamp holds very securely.The fans can be aimed independently over a wide range of angles.The power adapter plugs into the bottom of the controller and I had a tendency to pull it out by accident with my foot under the table where I have it plugged in. But I solved that by twisting the cable around the top of the controller as shown in the photo I attached.The blue LED is on all the time it's plugged in even if the fan is switched off. That helps you find the switch in the dark. If that bugs you, you could cover it with a piece of tape.----adding more. After a few weeks, I now have three. But two of them stopped working abruptly and had to be exchanged. Seems to be a problem with the controller. Obviously I'm not completely sure about that. I still like them a lot when they are working.

the first fans that i used for my grow tent had huge clips. they were so big and intrusive that they slightly stretched out the outer walls of my tent corners. i didn't think this was such a big deal until i noticed that they had stretched out the stitching and causing light leaks into my tent. MAJOR ISSUE if you're [ahem] growing what i'm growing! these have the perfect sized clips and pull some decent air. they're a bit on the pricey side, but for me it's worth it considering the risk reduction that they provide for me. if you're looking for something more practical, there are probably more affordable options out there for your cooling needs.i had to knock off 1 star due to a design flaw. in the event of a power outage, the fans run at a very low speed and repeatedly turn off and on once the power comes back. this is easily solved by manually turning them off and back on, but it can be a significant issue for your grow if you don't catch it soon enough.

My favorite feature is that you can configure it in any posible angle

I used this fan in a 2x4x5 grow tent with Cacti in it. It ran 24 hours a day almost non stop since January of 2021 and now its August of 2022. For the price, this is a great fan. If your building a small grow setup on a tight budget this is what you want, but make sure to get a good exhaust fan too.

Got this originally for summer camp, as a counselor I like to be a little extra. Then my car ac broke, so I used it in there until I got it taken care of. Now I use it next to my bed, because I like to freeze! Love this

Beautiful fan system for my 4x3 grow tent. Have been using it non-stop for 2 months now and no issues! Pushes a surprising amount of air and will definitely add another one to my setup soon!
