Review on 🌀 IETS GT202UB Vacuum Laptop Fan Cooler - Temperature Display, Intelligent Cooling, 13 Wind Speeds (2600-5000RPM Turbo Fan) - Ideal for Rapid Cooling of Gaming Laptops by Andrew Choukline

As mentioned, the "attachment" mechanism leaves a lot to be desired. It will not stay in place and should be supported and left alone. This of course defeats the purpose of using it on a MOBILE computer (laptop). The idea is good, the temperature sensor is good. It would be nice to know how to change from scale C to F. All instructions are in Asian language. Shame on Revain for allowing products to be sold in the US without English instructions.
