I have an older gaming laptop with only two functioning USB ports. This means I cant use my mouse, headphones, and external hard drive at the same time. I was previously limited to only playing games I could fit on my laptop itself and had to delete games to make space, download ones I wanted to play, and then delete them again when I wanted to play a different game. With this cooling pad I can now use multiple devices and actually have easy access to multiple games on my external drive to play with my friends. It is also far more efficient at cooling than my laptops fans and I can game for longer than ever. I am very happy with my purchase even though it is the most expensive cooling pad I have bought - its definitely much more useful than cheap 20 dollar Amazon coolers that are powered by USB and therefore would take up one of my desperately needed ports.
