I'm satisfied with this product.
It does what it says on the thin.
The only drawback is that the whole base is rotating,
which sounds as a cool feature, but for me it's really
inconvenient as it's rotates even when I'm typing this...
Maybe it bothers only me.
Otherwise, it's really silent, cools my laptop enough.
Before it was overheating all the time and kept shutting down.
Since I have this cooler, no problems at all.
I would recommend this, if the rotating is not disturbing you.
