Sturdy, Versatile, Easy to Install

Review by Jesse

I used this arm to mount two 24in monitors and the system handles them exceptionally well. This is definitely a heavy duty system. You can either mount the base through the desk or use the clamp that is included. It also has a laptop tray option to mount a monitor and a laptop instead or two monitors. The arms are a little stiff to move at first, so it's important to adjust the screws properly with the allen wrench that is included. It does take a little trial and error, but the arms move freely after all the adjustments are made. I like the fact that is the unit is sturdy and not flimsy at all.
