Review on 🔥 Zezzio Ultra Quiet Laptop Cooler: Powerful Cooling Solution for 12-17 Inch Notebooks by David Citizen

I ordered two. None match the image of where the knob is to the left of the fan speed controls. Instead, there is a pin-sized hole at the top with a QC sticker. This is shown in some marketing materials but not other images showing a button, presumably an LED button or controller? There is no button to turn off the LEDs, that's why I ordered it. To turn off the LEDs, you need to turn off the fans completely. Aside from not being able to turn the LEDs off independently from the fans or having a button or knob to adjust the LEDs as stated in half of the marketing material. , it is a silent cheap cooler. I had the exact same design in 2017 that worked almost 24/7 for 4 years to cool audio video equipment.
