I purchased the Antec NoteBook Cooler about a year ago when I purchased my notebook computer. I really like this device. It works very well to keep the notebook computer cool. My computer gets very hot after long period of usage but when I sit the computer on this device it does not heat up nearly as much. I mainly use this product when I have my computer on my lap. This product keeps it directly off of my legs so it does not heat up as much. It is a very quiet product and you can barely tell that it is on. It features two fan settings. The low setting is pretty much silent and the high setting moves a lot of air so depending on your need there is a setting that right.The device is powered by a USB port and the included cable is very nice. The cable has an adapter on it that allows the USB port to be used by something else even when the device is plugged in. My biggest complaint with the device is an annoying blue LED light that it has. This light indicates that it is on but I find it to be very annoying especially when I am using the notebook cooler and my computer at night.
