Out of the box, this is a deceptively light and simple laptop cooler: plug it into a powered USB outlet and go. Very, very quiet and does it's job so well that I can no longer fry eggs and bacon on my gaming laptop (I'm starving...lol). Height adjusts by flipping out two stable and sturdy legs plus the 6 blue light up LEDs makes it look cool. Easy to store, too, as it fits an average computer backpack. For the price, this is amazingly cool.
