The pros:
-refroidit well
-silencieux
correct -finishing
-3 USB ports (the fan takes 2 ports on the notebook to operate)
-the laptop does not slide
-Very well suited for a 17 inch
The -:
-a little too elevated (no way to lower the pitch)
the low -speed adjustable fan (we would love to increase more than that)
-a bit expensive
Overall I would recommend it.
