I rated it high cause were not comparing apples and oranges, we are comparing cooler pads to coolers. Really cooler pads have been out for a long period of time. In fact i know some one who uses a lkaptop as a desktop, i isult them so much

they finally getting a desktop but yer.
I honestly think these cooler pads are useless, but u have to give it to the makers for getting the cooling on.
PS al, u might have mis read, but i know that some tosibha laptops only allow 1 USB port to use 250mA, this takes 280mA, so if we wanted to use 12 volt instead of 5 volt we might come into supply issues.
