First it should be noted that this product is cheaper on Amazon than on the Dell site. Beautiful screen support we use professionally. The screens are independently adjustable for tilt, vertical and horizontal angle (it can be angled to not have a "flat wall" in front of you). The whole is very solid, with a screw fastening system on metal parts. A glicière allows to hide the son. Be careful though: the product is heavy because the foot is metal and it is solid, the foot is also 31 cm deep, which is much more than 2 screens each on his foot. Be careful that the workspace - table or desk) is adequately dimensioned.
