Quite good, the only problem is that the fan makes noise in some points. Also, it says it has 2 speeds but it only has 1

Well... Silent!!! Flexible although the bracket is not suitable for mounting on pipes, it is flat. It got me out of a difficult position for cooling the camera during prolonged shooting in hot conditions!!! 98 minutes of shooting in 4k resolution and even though the camera got warm, it did not overheat or shut down due to temperature as it had happened in the past. Really silent (the microphone doesn't pick it up), with metal fins although a little bulkier than I expected

It is not suitable for a car. Even when the sun hits the car at 30 degrees, it heats up the metal and throws the same heat at you when it starts (I had it in the passenger compartment and it still increased the temperature). Let's see how it will be at home, even though the motor makes noise. Edit: It is decent for home use.

I work the fan in full smoke conditions at an entertainment center and it helps me a lot. Great construction

It is very good, guys. I use it on my external hard drive and it has saved me

It saved us for the baby and our daughter in the car during the hot summer when even with air conditioning, the car was slow to cool down.
