Well... half!
The screen support seems solid and well designed, apart from the 180 degree limitation function.
Mind you, the black is not black but dark grey (although the part number is correct - 292 - and therefore consistent with the information on the Ergotron website).
I'm very disappointed with the 180-degree angle limiter, which only works on the single-screen stand but not on the double-screen stand! The stand is not made the same way. The manual clearly indicates the configuration of the limiter on the single screen doc and nothing for the double screen despite the notches on the feet which are of no use.
What a disappointment for such a price!
