Although it is a little narrower than my dell vostro 3700 that much warmer, and I live in the south of France in a house without air conditioning, but always open to the four winds, so at 25 ° generally summer This product fulfills its role. I am very satisfied. More like I always ask my computer on the thighs, I work in an armchair in the living room, the foam cushion, quite firm but nice, is very well studied. What happiness then. Certainly a little noise emerges but very dull, so insignificant compared to the intense heat to which I am now more subject ..... Any small problem: wire connecting the support ventilated too short a computer, so I can not place the USB jack on the same side as the power plug of my computer which is lateral. It broadens me all the size of the computer, it makes me two "ears" on top of the computer, but hey .... seen the product price can not be too demanding.
