Purchased the arc stealth pro and the add on to make dual monitor screen. Despite the heavy screen , the arm was able to hold it firmly and easily adjustable to liking for both height and angles.
Was uncertain if my computer set up would support my existing laptop plus 2 external monitors, I wanted the flexibility that this system provided. Easy to set up and with option to add a third arm, I now have two external monitors and waiting for the laptop tray to install the third. A flexible system that can handle all my needs. recommend it highly.
Second purchase of the monitor arms, definitely fussle free while installing. Also the another monitor to stack with the x315.
Bought this with an additional Arm to mount my Laptop using the Laptop Mount. Love it, as I previously had an Arc Stealth and the USB port/cables that came with it really takes up too much space and I changed to this where its simple and provides the function I need. Gives me an additional option to install additional Arm if needed in the future..
