The wall mounting dual arm screen mount (EA-MA-32114 Wall Mounted Gas Spring Monitor Arm) arrived promptly and is a neat piece of machinery that does everything it claims. The only reason there is a star missing is not the fault of this piece of equipment but a limitation I should have considered. With the desk flush to the wall, the closest working distance that can be achieved with 2 24" screens (short edges together) is over 30 cm from the wall. So, with a desk with a width of 60cm, the screens are uncomfortably close and one has to sit further away from the desktop, making typing a trifle awkward. So to recap the screen mounting system is excellent if you have a desktop 80cm or wider
