Review on 🚘 TN TONNY Dual Head Clip Fan for Vehicles or Home - 4 Inches Electric Car Clip Fans with 360° Rotation, 12V Cooling Air Fan with Stepless Speed Regulation by Bill Schlag

I was immediately very impressed with how quiet this fan is. I bought it for my home office. My wife quickly stole it from me. So I ordered another one. The fan is very quiet, especially at low speeds. But even at top speed, it's still pretty quiet. The two fans run at almost the same speed, but they are not synchronized, so there is sometimes a slight "interference effect". I almost never notice it, but when it does, I push the speed up a bit and it goes away. The hardware is very reliable. The clamp is very secure. The fans can be oriented independently at different angles. The power adapter plugs into the bottom of the controller and I had a tendency to accidentally pull it out with my foot from under the table where I have it. connected. But I solved it by twisting the cable around the top of the controller as shown in the attached photo. The blue LED lights up as long as it is connected, even if the fan is switched off. This will help you find the switch in the dark. If that bothers you, you can cover it with a piece of tape. ----add more. I'll have three in a few weeks. But two of them suddenly stopped working and had to be replaced. It looks like a problem with the controller. Of course I'm not entirely sure. I still love them so much when they work.
