Only two faults, one almost expected. The outer two screens tend to sag a bit and seem to keep dropping over time as the desk gets jostled, Not a huge amount, only a 2-3 mm but just enough to be annoying. The second issue is the arms aren't quite long enough to bring the sides screens around to 45 deg as I was hoping, any angle means one screen has to tuck slightly behinds the other, covering somewhat more than just the bezel.
