The most important have been said in the reviews. positive: - Rugged construction (a metal rod bent) - Also holds a 17.3-inch Laptop - By bending backwards remain usable under the laptop space, eg for documents, interim storage of keyboard etc.. - Height suitable for ergonomic viewing angle on laptop (! Not too high) negative: - Supplied rubber feet sticker goodbye at movement under load slightly (point deduction) - Metal is rather dull (acts in the photos rather shiny) (no point deduction) Scope: Increase the screen position when working with an external keyboard, then simultaneously improved ventilation. For typing on laptop already for ergonomic reasons not recommended (not really tried), then the structure can fall into the swing with a 17.3-inch laptop something.
