NO EXCEPTIONS.  This IS the best. Its made of high grade aluminum and is LIGHT, STURDY, QUIET and EFFECTIVE. It cost a lot compared to other coolers, but i say to you its worth DOUBLE the amount of money. When i read the manufacturers description they said that it decreases the amount of noise of a notebook. I said "Yea right." When i got it I ate my words. IT ACTUALLY MADE MY COMPUTER QUIETER. this product was one of the best things I have ever bought. My satisfaction is 10000%. I have so much good to say about it. (By the way, Im a honest customer and this is not biased at all.) Do not waste your time with anything else. Buy this is DEFINATLY worth it.
