This is a multi-screen support with a foot "vice", to reduce congestion at the most, who does his job. First unpacking: I was surprised by the size of both the cardboard, and both its content itself. Steel Steel ... yes, not a vulgar metal or aluminum cover, this is a base of steel, heavy, rigid ... I had this feeling of solidity which is not an impression. This is not indicated in the description, but that support is supplied with all hardware to attach 4 screens, and even hardware for curved screens. We can say thank you, this kind of hardware is not easy to find in DIY stores. Just as two keys are provided for mounting ... it lacks a screwdriver. Downside ... the installation instructions all in English ... The vise Foot, it can be adapted on any medium and for any desk top thickness. The noose again ... it's tough ... careful not to force too much tightening, otherwise your desktop tray that is broken before the vice. Personally, I recommend to put a small piece of carpet on the 2 clamping shoes, it will avoid damaging your desktop. Arms are adjustable, but not impossible to adjust the spacing of the screens, without increasing the depth. I take a star for this and only reason ... otherwise it's perfect. Thus I could put my screens to my viewing height, and save me clutter foot screens. My personal 18/20 rating.
Note that for the packaging, it is a little too light ... cardboard was delivered ... and ripped open under the weight of the support 2 packages were ripped, and a hole the size of a fist was visible and could see the box contents .... Fortunately more fear than harm, nothing was missing.
