Awesome cooler. Large fan. The cooling port on the front is great. I tried the Targus laptop cooler the u3 and this one definitely works the best for my 15.6 inch notebook. I don't mind the sound of the fan on high being louder then the computer one. I just want a good fan. All reviews on web say its great and I agree. The best part is with its design you can place it on any surface which is nice plus the fact it has usb port on side so your note wastine one on the notebook.

None really. It is big like the reviews say but light and easy to carry around with laptop on it.

Great cooler and like all the other reviews on the web this one is definitely the ones to grab.
