Have a good piece now 5 weeks in operation and have to say that I did not regret the purchase. The cooler consists of a solid housing and the 2 fans are also well positioned and quiet reserved. Notebooks up to 15 inches are relatively stable and non-slip on it. The USB - connections also sit on the right site and are perfectly adequate. Furthermore, one has, practically, 2 compartments mounted on the bottom, which can be opened sideways. In one there is a flexible USB - cable. Super thing, I think. The cooling performance is, as with almost all notebook - coolers, not as extreme. But you have enough and is definitely an improvement! Nevertheless, I, as I wrote above, not regret buying, I have one thing to complain about. Namely, the two fans at the bottom are not protected at all. But I do not know why so Revoltec has chosen for me is not acceptable. Have the problem resolved itself as I have each of the two fans donated a fan grill. Had but would have been nice wenns been equal so. That's why there's a star deduction. A BUY recommendation I can give anyway.
