The cooler works very effectively, you can switch between three programs (all fans of, 4 to small, 1 large on) which actually every laptop can be well chilled. The device also has an additional USB port, but it should be used for drives, XBOX controller gets too little power. You can adjust the angle and height.
1 star deduction for the volume, because the fans are quite noisy, and the description is not entirely accurate. I can hardly imagine that a 17 "notebook is well cooled, since a 16.4" covers the radiator completely
